Instruction-assert

Change-instruction-assert

Modifying constructor for instruction-assert structures.

Syntax

(change-instruction-assert x 
                           [:op <op>] 
                           [:arg1 <arg1>] 
                           [:arg2 <arg2>])

This is an often useful alternative to make-instruction-assert.

We construct a new instruction-assert 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.
