Tyspecseq-union

Make-tyspecseq-union

Basic constructor macro for tyspecseq-union structures.

Syntax

(make-tyspecseq-union [:tag <tag>])

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

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