Be careful with your use of $m as your variable as $m is typically
defined as a reference to the Mason request object. Confusing things
can happen if you use $m for something other than the Mason request
object. I've been there ;-)
The way I would tend to do this is only slightly different than what
is suggested above (assume that the checkbox field name is "cb"):
<%args>
$cb => undef
</%args>
if (defined($cb)) { # true if the checkbox is checked. }
if (!defined($cb)) { # true if the checkbox is not checked. }
