I am not sure I could with the way it's posted above because were you 
have a '1' would be a variable. So, I would have to rewrite my code to 
make another variable some how.  This is why I did:

$class{$position} .= "$pos" . " ,";

So, what would I enter in the place of a '1' if my $pos (a value) now 
becomes a key, as you've got posted above?

I guess I'll keep thinking about it. :-)
