The seemingly sane version could use some strictness. my $key = each %val makes no sense. The slightly more sane my $key = each %foo still makes no sense. each returns a list. $key is now always 2, unless it's 0.

Oh - try seeing what the stringification of %foo is, even when it's empty. It's not what you think. (And, even though overload has a hook for stringy, nummy, and booly - I'm pretty positive that scalars, arrays, and hashes all use the same values for each hook.)

Don't go borrowing trouble. For programmers, this means Worry only about what you need to implement.

Please remember that I'm crufty and crochety. All opinions are purely mine and all code is untested, unless otherwise specified.
