  2. Duck typing - Wikipedia

    en.wikipedia.org/wiki/Duck_typing

    Duck typing is similar to, but distinct from, structural typing.Structural typing is a static typing system that determines type compatibility and equivalence by a type's structure, whereas duck typing is dynamic and determines type compatibility by only that part of a type's structure that is accessed during runtime.

  3. Boo (programming language) - Wikipedia

    en.wikipedia.org/wiki/Boo_(programming_language)

    Boo is an object-oriented, statically typed, general-purpose programming language that seeks to make use of the Common Language Infrastructure's support for Unicode, internationalization, and web applications, while using a Python-inspired syntax [2] and a special focus on language and compiler extensibility.

  4. Structural type system - Wikipedia

    en.wikipedia.org/wiki/Structural_type_system

    Structural systems are used to determine if types are equivalent and whether a type is a subtype of another. It contrasts with nominative systems, where comparisons are based on the names of the types or explicit declarations, and duck typing, in which only the part of the structure accessed at runtime is checked for compatibility.

    In addition, it avoids the whole class of time-of-check-to-time-of-use (TOCTTOU) vulnerabilities, other race conditions, [28] [30] and is compatible with duck typing. A drawback of EAFP is that it can be used only with statements; an exception cannot be caught in a generator expression, list comprehension, or lambda function.

  7. Polymorphism (computer science) - Wikipedia

    en.wikipedia.org/wiki/Polymorphism_(computer...

    Dynamic polymorphism is more flexible but slower—for example, dynamic polymorphism allows duck typing, and a dynamically linked library may operate on objects without knowing their full type. Static polymorphism typically occurs in ad hoc polymorphism and parametric polymorphism, whereas dynamic polymorphism is usual for subtype polymorphism.

  9. Netstring - Wikipedia

    en.wikipedia.org/wiki/Netstring

    Rewriting the above "hello world!" example to instead be a sequence of two netstrings, itself encoded as a single netstring, gives the following: 17: 5: hello, 6: world!,, Parsing such a nested netstring is an example of duck typing, since the contained string ("5:hello,6:world!,") is both a string and a sequence of netstrings. Its effective ...
