Actually what I did was introduce two guard clauses. I am aware that it was correct in either fashion, it is my preference to have drop-through rules of the manner displayed previously. I also prefer explicit "false" return, and if there was some way I could say "return false" and get the same effect as just "return" I'd be using it :) undef isn't a bad concept tho.

Those are simply elements of my style however, the reasoning behind guard clauses is obvious in larger functions, in this case it is superfluous but assuming a reasonably efficient action on the part of the interpreter I see no likely efficiency loss, so the consistency rule applies :)

The re-use of the $range var is nice however.
