Reference-external

Make-reference-external

Basic constructor macro for reference-external structures.

Syntax

(make-reference-external [:get <get>])

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

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