Again this is the tricky part, the 'X' namespace hasn't been generated by the 'use'... it has been generated by the 'package X' in the file that 'use' loaded, which it is almost always acceptable to think of it as the 'use' doing it, because 'package X' will normally be the first thing in the file used, but technically not. Or do I have this wrong too? You could 'use X' and have 'package Y' at the top of X.pm and not end up with the 'X' namespace, but instead get a 'Y' namespace.
