Ex-args

Change-ex-args

Modifying constructor for ex-args structures.

Syntax

(change-ex-args x 
                [:term-lst <term-lst>] 
                [:fn-lst <fn-lst>] 
                [:fn-lvls <fn-lvls>] 
                [:wrld-fn-len <wrld-fn-len>] 
                [:expand-lst <expand-lst>])

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

We construct a new ex-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.
