Thank you for your reply, and thank you for your contributions to Perl. :-)
I've also built something similar, in the form of a data structure (hash
of WishfulThinkingListClass'es) that I use for holding arguments to
CGI::header(). I was hoping for an existing general-purpose type that I
could use and/or extend as required (such as arguments to CGI::redirect()).
What would be a suitable name for this type?
