CGI.pm is something I do bundle in - if not for the reason that certain versions of the CGI.pm module have bugs in it - if I know which version I'm targeting, I know how it will act - any quirks, etc.

Digest::Perl::MD5 seems to be exactly what I'm looking for - but it seems like its own docs are incorrect (in the synopsis at least) - it's namespace *is* Digest::Perl::MD5, and not Digest::MD5.

Other bundled modules, like CGI::Session, HTML::Template::Expr(?) that need Digest::MD5 won't find Digest::Perl::MD5.
