Hacking cperl-mode

Rummaging through Google groups, I came across this post:

I have two questions.  1. Is it possible to add something to my .emacs
file that would in effect override cperl-mode to change that final `t'
to `nil'?  (I suppose I could just hack a copy cperl-mode.el, and
rename it something like myperl-mode.el, but this is a problematic
solution) 2. What does the '$' mean in the regexp above?  The only
meaning I know for '$' in a regexp is as the end-of-line anchor, but
this interpretation doesn't make sense for this regexp.

Thanks in advance,
