Expression-const

Make-expression-const

Basic constructor macro for expression-const structures.

Syntax

(make-expression-const [:value <value>])

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

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