Escape-x

Make-escape-x

Basic constructor macro for escape-x structures.

Syntax

(make-escape-x [:get <get>])

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

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