* it doesn't require indexing so it is faster.
* it is the most standard way to get sub args.
* it easily allows for adding args by just putting another var
in the ().
* you can assign the rest of the args to an array or hash (after the
scalar args).
***** oh, it is also 1 char (not counting white space) shorter!
at least 4+ good reasons there! and not one downside reason i can think
of.
and those are also good reasons not to use shift on @_ except when it
really is needed.
