i'm 100% certain anyone who comes along to maintain my code...would start totally anew.

Personally I'd be less certain than that :-)

Anyway, I took a quick look at your code, and it looks like you're using parentheses on your function calls, which mitigates some of the parsing issues I touched on in Fun with Prototypes - as long as you're consistent in your style! But still, I'd suggest you look into Signatures instead of prototypes, which were discussed e.g. in this recent thread (Update: or some of the other options I mentioned).
