tcl...@li... is the best list.  I've cc'ed,
but you should join if you continue developing with it.

As to the questions, see the longer post I made to another person
in that thread where I reference your questions (anonymously).
The key item is that Tcl::Tk is still pre-1.0 for a reason, and
that the Perl/Tk compatability is weakest in the submodule area.

Learning a little Tcl will help, but it really isn't necessary to
make Tcl::Tk work for you - that's the point.  You should really
be able to work at the Perl level.  However, for compatability,
leveraging existing Tcl modules may well be to your advantage.
