Name+value

Change-name+value

Modifying constructor for name+value structures.

Syntax

(change-name+value x 
                   [:name <name>] 
                   [:value <value>])

This is an often useful alternative to make-name+value.

We construct a new name+value 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.
