  2. Scope (computer science) - Wikipedia

    en.wikipedia.org/wiki/Scope_(computer_science)

    In lexical scope (or lexical scoping; also called static scope or static scoping), if a variable name's scope is a certain function, then its scope is the program text of the function definition: within that text, the variable name exists, and is bound to the variable's value, but outside that text, the variable name does not exist.

  3. Common Lisp - Wikipedia

    en.wikipedia.org/wiki/Common_Lisp

    To understand what a symbol refers to, the Common Lisp programmer must know what kind of reference is being expressed, what kind of scope it uses if it is a variable reference (dynamic versus lexical scope), and also the run-time situation: in what environment is the reference resolved, where was the binding introduced into the environment, et ...

  4. Escape analysis - Wikipedia

    en.wikipedia.org/wiki/Escape_analysis

    In traditional static compilation, method overriding can make escape analysis impossible, as any called method might be overridden by a version that allows a pointer to escape. Dynamic compilers can perform escape analysis using the available information on overloading, and re-do the analysis when relevant methods are overridden by dynamic code ...

  5. Lisp (programming language) - Wikipedia

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

    Scheme is a statically scoped and properly tail-recursive dialect of the Lisp programming language invented by Guy L. Steele, Jr. and Gerald Jay Sussman. It was designed to have exceptionally clear and simple semantics and few different ways to form expressions. Designed about a decade earlier than Common Lisp, Scheme is a more minimalist design.

  6. Software verification - Wikipedia

    en.wikipedia.org/wiki/Software_verification

    Dynamic verification is performed during the execution of software, and dynamically checks its behavior; it is commonly known as the Test phase. Verification is a Review Process. Depending on the scope of tests, we can categorize them in three families: Test in the small: a test that checks a single function or class

  7. Late binding - Wikipedia

    en.wikipedia.org/wiki/Late_binding

    The name dynamic binding is sometimes used, [2] but is more commonly used to refer to dynamic scope. With early binding, or static binding, in an object-oriented language, the compilation phase fixes all types of variables and expressions. This is usually stored in the compiled program as an offset in a virtual method table ("v-table"). [3]

  8. Local variable - Wikipedia

    en.wikipedia.org/wiki/Local_variable

    Local variables may have a lexical or dynamic scope, though lexical (static) scoping is far more common.In lexical scoping (or lexical scope; also called static scoping or static scope), if a variable name's scope is a certain block, then its scope is the program text of the block definition: within that block's text, the variable name exists, and is bound to the variable's value, but outside ...

  9. Name binding - Wikipedia

    en.wikipedia.org/wiki/Name_binding

    Dynamic binding (or late binding or virtual binding) is name binding performed as the program is running. [2] An example of a static binding is a direct C function call: the function referenced by the identifier cannot change at runtime. An example of dynamic binding is dynamic dispatch, as in a C++ virtual method call.
