Expression-variable

Make-expression-variable

Basic constructor macro for expression-variable structures.

Syntax

(make-expression-variable [:name <name>])

This is the usual way to construct expression-variable structures. It simply conses together a structure with the specified fields.

This macro generates a new expression-variable structure from scratch. See also change-expression-variable, which can "change" an existing structure, instead.

                       nil))

Function: expression-variable
