Fundef

Change-fundef

Modifying constructor for fundef structures.

Syntax

(change-fundef x 
               [:tyspec <tyspec>] 
               [:declor <declor>] 
               [:body <body>])

This is an often useful alternative to make-fundef.

We construct a new fundef 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 . fundef->declor)
                           (:body . fundef->body))
