A few side comments:
Don't pass parameters like that, it's confusing: which shift gets executed first? I'd either use it if only one is involved at a time, and possibly if I have to use the rest of @_ as a whole, or stick with:
(I tend not to use $a and $b as general purpose variables even when they wouldn't be error prone because... their use is potentially error prone.) It's a commonly recommended style to put a semicolon on the last line too. Oh, and there's no need to use prototypes. Actually many people deprecate them. I find them useful for code and autorefs, but other than that they don't buy you much.
&-form of sub call is now obsolete and most likely not to do what you want. Read more about this in perldoc perlsub.
