Expr/tyname-expr

Make-expr/tyname-expr

Basic constructor macro for expr/tyname-expr structures.

Syntax

(make-expr/tyname-expr [:expr <expr>])

This is the usual way to construct expr/tyname-expr structures. It simply conses together a structure with the specified fields.

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