Fun-info

Change-fun-info

Modifying constructor for fun-info structures.

Syntax

(change-fun-info x 
                 [:params <params>] 
                 [:result <result>] 
                 [:body <body>])

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

We construct a new fun-info 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.

                           (:result . fun-info->result)
                           (:body . fun-info->body))
