Fun-declon

Change-fun-declon

Modifying constructor for fun-declon structures.

Syntax

(change-fun-declon x 
                   [:tyspec <tyspec>] 
                   [:declor <declor>])

This is an often useful alternative to make-fun-declon.

We construct a new fun-declon structure that is a copy of x, except that you can explicitly change some particular fields. Any fields you don't mention just keep their values from x.

Definition

This is an ordinary change- macro introduced by fty::defprod.

                           (:declor . fun-declon->declor))
                         'change-fun-declon
                         'nil))
