Amb?-expr/tyname-ambig

Change-amb?-expr/tyname-ambig

Modifying constructor for amb?-expr/tyname-ambig structures.

Syntax

(change-amb?-expr/tyname-ambig x 
                               [:expr/tyname <expr/tyname>])

This is an often useful alternative to make-amb?-expr/tyname-ambig.

We construct a new amb?-expr/tyname-ambig 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.
