I'd like to see this specced. What you're suggesting is that sub
signatures have something as powerful as a good getopt library; things
that spring to mind at this prospect are:

* canonical representations (eg, :w in your example should probably set

* mutually exclusive options (for open modes, :write should exclude

* computed options (if by "let Perl figure that out" $mode you didn't mean
  "let perl's open figure it out with explicit code).

How would you suggest formalizing these?

(By the way, we need a spec for perl's command line, too. So far we've
been emulating perl5's in an ad-hoc manner.)
