Fundef

Change-fundef

Modifying constructor for fundef structures.

Syntax

(change-fundef x 
               [:name <name>] 
               [:inputs <inputs>] 
               [:outputs <outputs>] 
               [: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.

                           (:inputs . fundef->inputs)
                           (:outputs . fundef->outputs)

                         'nil))
