provides same functionality as Perl/Tk, but makes available much more richier widget set (all widgets in Tcl/Tk distribution, including pure-Tcl and other widgets).
Both perlTk and pure-Tcl syntaxes are available.
Allows to perform GUI design in any Tcl/Tk designer (say, vtcl from vtcl.sourceforge.net) and use that GUI from Perl seamlessly.
Also it is fast to startup and quick to redraw.
I am co-maintainer of this module.
