Expression-var

Make-expression-var

Basic constructor macro for expression-var structures.

Syntax

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

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

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