You don't need switch to replace this code:
$y = $x; # poof!
However, Perl has various ways of doing things like switch, see perldoc -q
switch or
http://www.perldoc.com/perl5.6/pod/perlfaq7.html#How%20do%20I%20create%20a%20switch%20or%20case%20statement%3f.
This was discussed recently in another thread.

'if $y' and '$y > 0' are testing for slightly different things. The
equivalent would be '$y and y()'.
I've always taken perlstyle's advice to keep the important part up front.
The condition here is not as important as the action taken.
