The fact that you can modify the vrbl passed to a sub from in the sub without

This aliasing provides a C++-like passing by reference, but it's true
that it isn't Perl references... I agree with the "exercise in
semantics". :-)
(NB : You're perfectly right that this syntax is dangerous and to be
used only by the peoples who know what they're doing, I just pointed
that this was a possibility)
