least more tightly than comma and possibly very tightly) and convert a
number to one of these objects, so that we can do stuff like this:
substr($string, 2 bytes, 4 bytes) = $substitute;
Then if you pass a plain number to substr it could either assume
The word "bytes" is clearly much too long, though, much less
