Well, syntax aside, how would this work?

Does the presence of an ordering subroutine cause perl to generate a
linked list of all the elements of the %hash in the proper sequence
prior to iteration (and somehow attach it to the iterator)? Seems
like everytime we did that it would generate a new operator:
while (my ($key, $value) = each alphabetic %hash) { # 1
while my ($k2,$v2) = each crazy_order %hash) { # 2
...
}
}
At #1, the iterator would really be an each_alphabetic and #2 would really
be an each_crazy_order rather than a generic iterator. (Unless you really
want the iterator to compute the next in sequence on each iteration)
