Const-expr

Make-const-expr

Basic constructor macro for const-expr structures.

Syntax

(make-const-expr [:expr <expr>])

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

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