in reply to my least favorite perl feature
What is "overloaded" by design in perl is two possible values for every scalar: a string or a number. The comparison operators let you choose which. Do you want to give up either lexical or numeric sorting by overloading "<=>"?
By the way, if you "use warnings" perl will help you out, like so:
Argument "bbb" isn't numeric in numeric eq (==) at ddd.pl line 4.
