I'm not happy about the behaviour of join here, because there is no way how CORE::join() will ever assign to the lvalue.<P>
So it should act like handling copies.<P>
I'm aware that we can override built-ins like join, so accessing the alias should still be possible. Theoretically that is.<P>
<H5> Update</H5><P>
On second thought, a general new <tt>Warning</tt> in case of side effects of altered repeated variables as arguments may be more effective.<P>
