A conforming implementation is really two lines of code. It's fun to
write, but admittedly of limited usefulness, in that I would think in
properly designed code the needed number of elements would be already
exposed through a named constant. So, the only cases where I can
imagine this to be useful is either when you need the count of the
array to play some unorthodox trick, or when you have third-party code
that "forgot" to expose the right constant.

Genny.
