This is the first mention I have heard of "dereferencing" a variable. I was looking for it in perldoc and found some references to it, but wish to double check what I have gathered. It seems to me:

&{ $functions{$doit} };

Would be seen by Perl as:

"Take the value of $functions{$doit} and treat it as a sub name"

Is that about right?
I also keep seeing the use of my $thing = $q->param('whatever'); but am having trouble searching for it as I do not know what name it goes by...

Thanks, for the help and better code.
