  Yet Another Language Geek : Types of confusion
Maybe, a claim could be made that dynamically typed languages tend to be more terse given languages like Python, Perl, and Lisp; however, the statically typed languages have some very terse representatives as well (Haskell, ML dialects).
In fact, most statically typed languages have a few features that are dynamically typed.
Despite this, a language is usually referred to as being either statically or dynamically typed.

  Datatype - Wikipedia, the free encyclopedia
Static typing advocates believe programs are more reliable when they have been type-checked, while dynamic typing advocates point to distributed code that has proven reliable and to small bug databases.
Advocates of strongly typed languages such as ML and Haskell have suggested that almost all bugs can be considered type errors, if the types used in a program are sufficiently well declared by the programmer or inferred by the compiler.
Static typing allows construction of libraries which are less likely to be accidentally misused by their users.

 Programming language - Wikipedia, the free encyclopedia
Statically typed languages can be further subdivided into languages with manifest types, where each variable and function declaration has its type explicitly declared, and type-inferred languages.
With statically typed languages, there usually are pre-defined types for individual pieces of data (such as numbers within a certain range, strings of letters, etc.), and programmatically named values (variables) can have only one fixed type, and allow only certain operations: numbers cannot change into names and vice versa.
Most mainstream statically typed languages, such as C, C++, C#, Java and Delphi, require all types to be specified explicitly; advocates argue that this makes the program easier to understand, detractors object to the verbosity it produces.

 [No title]
Static typing in reflective systems is useful since it precludes breaches of type safety through self-interpretation; we cannot construct a syntax tree that causes a run-time type error when we interpret it.
Haskell static typ- ing with parametric polymorphism and systematic overloading.
We argued [7] that conventional statically typed object-oriented lan- guages were not sufficient to guarantee well-typed expression syntax trees and described an alternative metalanguage based on F-bounded poly- morphism [1] and existential quantification [8].

 Static Options
When a statically typed object is assigned to a statically typed variable, the compiler can check to be sure that the types are compatible.
However, when a message is sent to a statically typed object, the class of the receiver is known by the compiler.
Static typing can free identically named methods from the restriction that they must have identical return and argument types, but it can do so reliably only if the methods are declared in different branches of the class hierarchy.

C, Java, ML, and Haskell are statically typed, whereas Scheme, Lisp, Perl, PHP, Visual Basic, Ruby, and Python, are dynamically typed.

A compiled language is a vague term referring to a language whose implementations are typically compilers (translators which generate machine code from source code), and not interpreters (step-by-step executors of source code, where no translation takes place).

 Are Dynamically Typed Languages The Next Big Thing? [ ZefHemel.com ]   (Site not responding. Last check: 2007-10-29)
In a way you get the feeling dynamically typed languages are so much more simple and productive than the statically typed ones, on the other hand you see their problem: tooling.
Statically typed languages are languages that that force you to explicitly state the (return) types of your variables, functions and parameters.
Another difference between the interpreters/compilers of dynamically typed languages and statically typed languages are the errors they detect on “compile” time (or in case of interpreters, before something gets actually run).

This positive experience with traits in the untyped Smalltalk world suggests that traits may be useful in statically typed languages too.
In this paper, we present a statically typed calculus of traits, classes, and objects, which can serve as the foundation for extending statically-typed class-based languages, such as Java, with traits.

 Why type checking?   (Site not responding. Last check: 2007-10-29)
In a strongly typed language, the language implementation is required to check the types of operands in order to ensure that nonsensical operations, like dividing the integer 5 by the string ``hello'', are not performed.
In a statically typed language, every expression of the language is assigned a type at compile time.
One possible disadvantage of static typing is that because static type checkers are necessarily conservative, a static type checker for a programming language may disallow a program that would in fact execute without error.

 Chapter 11, Outline   (Site not responding. Last check: 2007-10-29)
In a statically typed language we say the class of the declaration is the static class for the variable, while the class of the value it currently holds is the dynamic class.
Most statically typed OO languages constrain the dynamic class to be a child class of the static class.
The static class is the class of the declaration, the dynamic class is the class of the value currently held.

 Strongly typed, weakly understood   (Site not responding. Last check: 2007-10-29)
Static vs dynamic typing describes at what point type analysis (determining whether a programmer's request to perform a particular operation is permissible) happens: at compile time for a statically typed language, or at run time for a dynamically typed one.
Statically typed languages often require type declarations in programs, however some statically typed languages such as ML can in some cases infer types from the operations performed, making manifest type declarations unnecessary.
Comment on Strongly typed, weakly understood by David Buck Manifest typing is normally considered a specialisation of Static typing, so if it's manifest typed, it ust be (by definition) also statically typed.

 Programming language - Wikipédia
Sometimes type-inferred and dynamically-typed languages are called latently typed.
With statically-typed languages, there usually are pre-defined types for individual pieces of data (such as numbers within a certain range, strings of letters, etc.), and programmatically named values (variables) can have only one fixed type, and allow only certain operations: numbers cannot change into names and vice versa.
Ada, Java, ML, and Python are examples of strongly typed languages.
