Statement-increment

Change-statement-increment

Modifying constructor for statement-increment structures.

Syntax

(change-statement-increment x 
                            [:mapping <mapping>] 
                            [:index <index>] 
                            [:amount <amount>])

This is an often useful alternative to make-statement-increment.

We construct a new statement-increment 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.
