Thanks, I like the idea (would have dismissed it if I came up with it
myself but - in the end the std:vector would add indirections as well, and
the array lookup should be pretty cheap since it's only the integer part of
the array.
Just saw your message about the metatable on top of it, it seems I have
something to play with!
