That seems kind of like a reinvention of Array#index, though.  It also
has the usual problem with rescue, i.e., that you might rescue the
wrong thing (if nonzero? is mistyped or whatever).  Do you see an
advantage to doing it this way, rather than the index/detect way?
(I'm being lazy and not benchmarking them....)
