if we have no cast, I find the version without the patch just fine.
If we have a cast, I suggest we just express the result in bytes, something
along those lines (inspired by your suggestion):
array index $count is $(bytes - end_of_array_in_bytes) bytes past the end
of the allocated memory for that array (which contains $end_of_array_in_bytes
bytes)
