ANSI Common Lisp  3 Evaluation and Compilation 3.1 Evaluation
3.1.1 Introduction to EnvironmentsA binding is an association between a name and that which the name denotes. Bindings are established in a lexical environment or a dynamic environment by particular special operators.An environment is a set of bindings and other information used during evaluation (e.g., to associate meanings with names). Bindings in an environment are partitioned into namespaces. A single name can simultaneously have more than one associated binding per environment, but can have only one associated binding per namespace. |
