Method and apparatus for providing dynamically scoped variables within a statically scoped computer programming language

摘要

A programming language is provided that permits the use of both dynamically scoped variables and statically scoped variables, and that allows a programmer to select which scoping is desired for a particular variable. The programming language comprises at least one language construct for defining statically scoped variables to be used if a static scoped variable is desired and at least one language construct for defining dynamically scoped variables to be used if a dynamically scoped variable is desired. A method, apparatus, and computer-readable medium are also provided.
