SPUG: "Clobberation" in ($c,$d)=($d,$c)

During the Q&A session at the Perligata meeting, someone mentioned that
if you alias a variable and then use it on one side of a variable
switch, you get "clobberation". I was thinking about that tonight and
decided to take a look, but I couldn't reproduce it.
If memory serves, the problem was with constructs like:
*e = \$c;
($c, $d) = ($d, $e);
But that seems to work fine, so I must be remembering wrong. Can someone
refresh my memory?
Thanks!
