Fhg-args

Change-fhg-args

Modifying constructor for fhg-args structures.

Syntax

(change-fhg-args x 
                 [:term-lst <term-lst>] 
                 [:fn-lst <fn-lst>] 
                 [:fn-returns-hint-acc <fn-returns-hint-acc>] 
                 [:fn-more-returns-hint-acc <fn-more-returns-hint-acc>] 
                 [:lambda-acc <lambda-acc>])

This is an often useful alternative to make-fhg-args.

We construct a new fhg-args 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 defprod.
