in thread Can I check if a loop's scope is entered for the first time?
No question. It would definitely be better.
Unfortunately, there's no way to give each_value() a prototype
that allows it to also take a thunky block as an argument...in addition
to all the other argument types (hash, array, reference) it currently takes.
The current declaration is:
sub each_value (+) {...}
but, to be able to accept a block it would require:
sub each_value (&) {...}
and there's no prototype marker than allows both. :-(
