Me too. I would assume that 'count' counts array elements whereas 'size' counts the number of bytes the array uses up. IMAO, this sort of "write your mind and somehow it just works" thing only encourages lazy programming (guessing what something does without knowing for sure, and copy-n-pasting code without understanding it, which leads to bit rot and hideous patchwork code that houses all sorts of subtle bugs and corner-case failures).
