Expr-ident

Change-expr-ident

Modifying constructor for expr-ident structures.

Syntax

(change-expr-ident x 
                   [:ident <ident>] 
                   [:info <info>])

This is an often useful alternative to make-expr-ident.

We construct a new expr-ident 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.
