I'm not a language lawyer, but I'd be /very/ surprised if it where in
the spirit of the ANSI spec that you could "extend" functions at your
whim.  As a data point, look at the dictionary entry for DIRECTORY
which specifically allows implementations to add keyword parameters to
the function.  Why would that passage be in there?
