[Templates] creating dynamic hidden fields in templates

You know, rather than do the above, which irked me, I did the following:

$Template::Stash::SCALAR_OPS->{ join } =3D sub { return shift; };

Which adds a nice join method to the scalar and thus saved my sanity. =

Maybe you'll like that more? It returns a proper undef when the scalar =
is undef, rather than an empty list being passed to join so that may =
help CGI avoid your empty hidden field issue.

Worth trying anyway. =3D)
