摘要: A problem common to many powerful programming languages arises when one has determine what values assign free variables in functions. Different implementational approaches which attempt solve the are considered. The discussion concentrates on LISP implementations and points out why most current systems not as general original 1.5 system. Readers familiar with should be able read this paper without difficulty since we have tried couch argument ALGOL-like terms much possible.
