	Type safety in Nice
		One of the limitations of Java is the absence of genericity: classes and methods cannot have type parameters.
		Type checking guarantees that the array will not be written to by this method, so that there will be no run time failure.
		Partial solutions exist, notably using dependent types, but they are not ready for widespread use because of their high complexity.

	Type safety - Wikipedia, the free encyclopedia
		The behaviors classified as type errors by any given programming language are generally those that result from attempts to perform on some value (or values) an operation that is not appropriate to its type (or their types).
		Most statically-typed languages provide a degree of type safety that is strictly stronger than memory safety, because their type systems enforce the proper use of abstract data types defined by programmers even when this is not strictly necessary for memory safety or for the prevention of any kind of catastrophic failure.
		Type safety is synonymous with one of the many definitions of strong typing; however, type safety and dynamic typing are not mutually exclusive.

	Re: type safety
		types: syntactic expressions which are associated with program fragments according to a set of typing rules and which (if the rules are sound) represent propositions satisfied by the program fragments.
		Safety does have _something_ to do with types, in the following sense: If a programming language has unsafe programs, then it is always possible to define type systems which will exclude all of the unsafe programs.
		I disagree strongly with the thesis that: Type structure is a syntactic discipline for enforcing levels of abstraction.

	type system terminology
		Static typing is when types are assigned to the elements of a program’s code, such as its variables and expressions.
		Type safety is used to describe an operation or construct that cannot violate the rules of the type system.
		For example, the C type casting operator is not type safe because it allows you to mix totally incompatible types.

	Type Safety (Ch. 2, Sec. 10) [Securing Java]
		Type safety means that a program cannot perform an operation on an object unless that operation is valid for that object.
		Type safety checks ensure that any object a method may try to manipulate is of the proper type.
		Type safety guarantees that programs will not do terrible and dangerous things such as treating pointers as integers (or vice versa) or falling off the end of an array.

	RE: type safety
		Safety is an internal consistency check on the formal definition of a language.
		Essentially each type determines a "canonical" property of values of that type, which turns out to be true of all values of that type.
		Such properties (sometimes, rather misleadingly, called a "soft types" or a "refinement types") are interesting and important, but they are only rarely part of the fundamental type system of the language.

	eLCOSH : Ladder Safety
		Ladder safety begins with the selection of the proper ladder for the job and includes inspection, setup, proper climbing and standing, proper use, care, and storage.
		In addition to the general safety rules for all ladders there are special rules for using stepladders and for single and extension ladders.
		Type IA and Type I ladders are the only acceptable ladders on a construction jobsite.

	Built-in Type Safety?
		Programmers inform their compiler about the types they are using.
		Some variation in the signal is to be expected, depending on location, atmospheric conditions and so on; but if a more substantial change occurs then the new value must be stored in RAM and written to flash memory.
		Perhaps it would be more accurate to say that the C type system failed to help since this is one of those areas where C++ finds itself compromised and constrained by its C heritage.

		Type safe means preventing programs from accessing memory outside the bounds of an object's public properties A programming language is type safe when the language defines the behavior for when the programmer treats a value as a type to which it does not belong.
		Type safety requires that well-typed programs have no unspecified behavior (i.e., their semantics are complete).

		Type errors are possible in well-formed programs (and do not require use of explicit constructs which "waive" typechecking).

	Type-safety of Lava
		In the presence of multiform types and type parameters the semantics of the statement "object x conforms to type Y" has to be reconsidered.
		If the declared type T of a variable var is multiform and depends on virtual types then the actual run time meaning of T depends on the actual pattern context that has to be applied at run time at this place where var is referenced.
		A multiform type is a type whose declaration is contained in a pattern.

	Static Type Safety
		Static type safety is the single most accessible form of systematic formalization commonly available in programming languages.
		In dynamically typed languages, the data type is a property of the object itself.
		Well, you can't trick the Java VM either, and it is essentially uninteresting from a developer's perspective to where type information is attached (to the reference, or to the memory location), as long as it assures safety.

	Type safety conditions
		We desire a type system which permits secure, type-safe, implementation of imperative routines without simply imposing the unnecessarily harsh restriction that the programmer may only make references to monomorphic values.
		The problem of designing a permissive type system for imperative programming has proved to be one of the most difficult in the history of programming language design.
		A programming language which infers types should not make the types of functions so complex that a programmer can no longer have reasonable conviction about the type to expect to see reported by the compiler.

	Java Arrays Break Type Safety
		This breaks type safety, and therefore array accesses have to be type checked at runtime.
		Java already suffer from primitive types not being objects and thus requiring separate handling of each of 8 or 9 types of them in generic algorithms.
		The real pain of Java only completely enforcing type safety for arrays at run-time is that there is a run-time cost to array accesses, even though no sane code will ever fail the test.

	The Truth about Type Safety in Programming Languages
		The lack of type safety in C and C++ is probably useful for low-level programming, bit-twiddling.
		The first two definitions could equally be applied to type systems such as Lisp's because the types of values are easily recognized and evident to the run-time system whereas types declared at compile-time are implicit at run-time.
		The third definition, that of a manifest as a list of goods, could be applied to compile-time type systems because the declarations of variables and their types could be interpreted as a manifest, but the information about values and their types at run-time is a manifest for the run-time system.

		It works like this: the class file erases the information about the real type of the object - all it knows is that it's an instance of AbstractNodeType, so casting to it is not a real casting.

	Type system - Wikipedia, the free encyclopedia
		A programming language is statically typed if type checking may be performed without testing equivalence of run-time expressions.
		A language has a compile-time phase if separate modules of a program can be type checked separately (separate compilation), without information about all modules that exist at run time.
		A programming language is dependently typed, if the phase distinction is violated and consequently the type checking requires testing equivalence of run-time expressions.

		One simple way to enforce type safety would be to check an object's type tag before every operation on it to make sure that the object's class allows such an operation.
		Static type checking is where the Java system looks at a program before it runs and carefully deduces the results of the tag-checking operations.
		There are no "generic" operands that take multiple types in the same operand position, as is the case with processor assembly languages.
