Re: just how special are $a and $b these days?

perldoc -f sort has a vast amount of information on writing sort subroutines.

But if all you want to do is use a function from some random module to do the comparison, how about ...

@output = sort { Some::Module::comparison($a, $b) } @input

Or, if you really want to, you can overload `cmp` as a call to `Some::Module::comparison`, and then as long as `$a` and `$b` are objects of that module, they'll sort automatically.	[reply] [d/l] [select]
