Indeed. I see this bite people regularly at $work (non Perl
programmers converting seem to get bitten by each() at least once in
their career).
In the case of hashes I think tying it to the op would also be bad.
I kinda wish perl had an interface like
my $iter= iterator(%hash);
while (my ($key,$value)= $iter->each) {
}
Which I think would be sane. You could even pass the iterator without
passing the hash itself. (Preventing modifications to the hash but
allowing 3rd party code to iterate it).
