The argument processing that you are doing here suffers from the problem that if someone calls your function and has a typo in their hash key, there is no check for it. Also people cannot choose to explicitly use false values. At the expense of considerable overhead, the approach I describe at Re (tilly) 2: passing subroutine arguments directly into a hash solves both problems.
