Whoops, I just looked again and it appears that while this store does
occur, it's not inside the loop.  So my benchmark was indeed worthless.
I guess I'll try another version of it that performs some calculation inside
the main loop that can't be optimized away.

Any light you can shed on the core issue (whether __index and __newindex
that look up a method can be as efficient as straight method calls) would be
most helpful!
