If you read my other emails, you'd note that in my case I do not have
program arguments unattached to switches, and I am not arguing for this
being the one way everyone should always do things.  (Nor am I saying this
is the one way I intend to always do things, nor am I saying this is
in general the better way.)

Easy: the same way that Getopt::Long does it.

The same way that Getopt::Long does it.

Searching CPAN for 'Getopt' yields 39 modules.  There Is More Than One
Way To Do It.  And all I'm asking is if anyone knows if any of them does
what I'm describing.  (Presently, I'm looking at Getopt::Declare,
which apparently permits the following:

        -pages 1
        -pages 1 2 7 20
	--window <height> x <width>

It's written by some Australian guy you probably haven't heard of.)
