Egg on face. Much gnashing of teeth. I was under the impression from the
limited documentation in 'perldoc constant' that you could only supply array
refs to constant definitions, not lists.

This was reinforced by a bad experience I had when I first started using
constants...

use constant FOO => 1, BAR => 2, OBO => 3;

which didn't do __at all__ what I expected. Anyway, I'm edumacated now, so
I'll slink off, still muttering about constant.pm's cruddy documentation...
