Just as a note: it's usually a much better idea to write your test cases 
first, even before writing any code.  It'll give you a better idea of what 
you want your function to do.

(It'll also probably give the other here a better idea of what the 
function is supposed to do.  I myself don't quite know either what it's 
supposed to do based solely on the description.  *grin*)


What are some small test cases you're thinking of for this function?
