Var/const-dinfo-option-some

Change-var/const-dinfo-option-some

Modifying constructor for var/const-dinfo-option-some structures.

Syntax

(change-var/const-dinfo-option-some x 
                                    [:val <val>])

This is an often useful alternative to make-var/const-dinfo-option-some.

We construct a new var/const-dinfo-option-some 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.
