Regex-concat

Make-regex-concat

Basic constructor macro for regex-concat structures.

Syntax

(make-regex-concat [:lst <lst>])

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

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