Const-enum

Make-const-enum

Basic constructor macro for const-enum structures.

Syntax

(make-const-enum [:ident <ident>])

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

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