Yes agree with Rob on this one. I have been using 0 based indexes for a
long long time, but when i see find_nth(), I expect 1 to be the first
I think in this case naming guidlines should override convention or
usage concerns. If you use a term like "nth" in the name, it should
reflect its usage in the english language.
