Out of curiosity, have you ever needed this? I use the one-dimensional 
function all the time, but I've never, ever, needed to obtain "the 3rd 
size".

By the way, Microsoft seems to be pushing _countof( x ) as a name for this 
functionality, probably with the intention to make it countof if it gets in 
an official C or C++ document one day. I've always used array_size or just 
size, but countof isn't bad.
