Yes, it would be nice to be able to round trip these
values better.  I think the first run would be to clean
up how the module creates commands and vars in Tcl (use
a ::perl namespace, where we can also create our own
stuff like ::perl::eval).  Later on we could look into
creating our own object type in Tcl to wrap Perl SVs, so
we never lose touch either way.

This is just another couple of print statements cased on
DEBUG, no?
