	PEP 252 -- Making Types Look More Like Classes
		For example, you can't directly subclass the dictionary type, and the introspection interface for finding out what methods and instance variables an object has is different for types and for classes.
		The class-based introspection API is used primarily for class instances; it is also used by Jim Fulton's ExtensionClasses.
		The type API is sometimes combined with a __dict__ that works the same as for instances (for example for function objects in Python 2.1, f.__dict__ contains f's dynamic attributes, while f.__members__ lists the names of f's statically defined attributes).

	E. B. Titchener: The Type-Theory of The Simple Reaction (Site not responding. Last check: 2007-10-18)
		There is a psychological disposition involved in regularity of reaction : and the obtaining of the sensorial-muscular types may be regarded 'as averagely characteristic of it.'—The theory of the reaction itself, as I said just now, is quite a different matter.
		But it is plain enough that we cannot infer type from reaction, whatever may be the effect of type upon reaction, given equality of all other conditions.
		Type may shift in other ways : it is possible to break oneself of the habit of piano playing by finger-memory, and to learn to "read," i.e.

		For the types that remain, either there is a one-to-one mapping into one of the language types, as is the case for IDL doubles, or the scripting language must implement a native class which correctly wraps the IDL type.
		We mark the types that are mapped natively, the ones that are converted, and the ones that are wrapped by a native object/class instead.
		Typing is dynamic and conversions among types are automatic, which means the script writer does not have to worry about types.

	Extensions to CodeWarrior Pascal
		It is possible to declare an anonymous type in the interface part of a unit and leave the actual declaration of the type for the implementation.
		The corresponding type declaration in the implementation needs to be a pointer to some type or an object.
		It is often necessary to perform type introspection at runtime to prevent problems, to this effect a method called isMemberOfClass, declared in NSObject, checks whether the object instance is an instance of a particular class.

	Typology: Comments on Four Letter Type Distinctions
		Nor does this mean that Introspector types are unaware of the objects around them -- not at all -- but simply that they are more inclined to become absorbed in their ideas.
		On the other hand, Introspectors practice introspection much of their time, and with pleasure, but the penalty they pay for this is that they can end up with relatively undeveloped observational abilities.
		For both types, the vitality, the immediacy, and the significance of life is found more easily in their own world, while what is central to the other's world seems relatively foreign, uninteresting, and unimportant.

		From these, checked by special experiments the experimenter ascertains the type of memory employed, a new set of experiments is then begun, in which the subject is told to remember in a particular way, different from the way of least resistance.
		The type theory would hardly be a theory of the geistige Anlagen which it presupposes, even if it fitted all the reaction facts.
		It surely posits memory type; it does not state the conditions under which one or other type may be looked for.

	Naked Objects \| Lambda the Ultimate
		More concretely, when I define a type T in the local scope, I should be able to syntactically specify that the compiler should generate a data structure describing T's layout (call it T.metadata, for example), and to make that data public or private.
		But, given just a value of some arbitrary type, one should not be able to extract its "type", since that notion violates many universal properties (such as the subtyping property).
		Typeable a ⇒ a lets you check whether a is a type you're familiar with, but doesn't give you any extra information if it isn't; and ∃a.

		There are lots of use cases for introspection, so I wonder why there is introspection for facets, but not for receptacles or event ports.

		The types used for facet and receptacle introspection are also updated in order to achieve a consistent interface for all types of ports.

	Re: OO polymorphism
		This is a semantic distinction, whether types play a role or not in the evaluation.
		And if an operation uses directly the type of an object to access its representation, it might be unable to work properly on one of its subtypes.
		This can also be seen as adequation between the type system and the language: if a language has both inclusion polymorphism, and allows uncontrolled type dispatch, you may easily loose type safety (cast failure).

	:: Welcome to Cognition - Third Edition - Exploring the Science of the Mind ::
		This is because, as one concern, introspection relies on what people remember about their own mental processes, and we cannot count on these memories being reliable.
		In addition, introspections are usually reported verbally: The person describes what happened in his or her own mind.
		In Chapter 11, we noted that there are complexities attached to someone's introspective reports about the vividness of his or her own images, but we argued that these vividness reports are nonetheless an important source of data about images.

		Apart from some fundamental types like strings, integers and so on, type information must be compiled into applications prior to execution.
		Some, for example, let developers promise not to change the type of a variable at run-time and thus allow the compiler/interpreter to be cleverer in its dealings with the variable both at compile time and at run time.

		It returns a list where the second element is the name of value's object type, or "none" if there is no internal representation.

	Psychology of Consciousness (Psyc. 358)
		• Most introspection is informal, but in research, people may be asked to do formal introspection in a systematic manner and report their inner observations as precisely as possible.
		• Introspective verbal reports are intended to be reports on the subject's conscious experience per se, including contents and mental processes related to the task, and on daydreams unrelated to the task.
		The fact that introspective reports cannot be verified is the major reason why they have been rejected by many as a research method.

		A type code is an ASCII character representing the type of a value.
		A single complete type is a basic type code, a variant type code, an array with its element type, or a struct with its fields.
		The restrictions are: it occurs only as an array element type; it has exactly two single complete types inside the curly braces; the first single complete type (the "key") must be a basic type rather than a container type.

		Type is roughly equivalent to class, and property is roughly equivalent to field.

		If a value is submitted, it returns a list where the first element is the name of value's object type, or "none" if there is no internal representation.
		The second element is a boolean stating if the object has a valid string representation.
