Function-specification

Change-function-specification

Modifying constructor for function-specification structures.

Syntax

(change-function-specification x 
                               [:name <name>] 
                               [:functions <functions>] 
                               [:specifier <specifier>])

This is an often useful alternative to make-function-specification.

We construct a new function-specification 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.
