Very interesting. (And yet another item for the language comparison pages, 
at least until Perl 6 possibly materializes a couple of years from now.) 

# Tk is a good fit for very simple applications.

That was certainly my experience with Perl/Tk some years ago.

However, in anticipation of a "Which Ruby/GUI should I use?" FAQ entry 
(which I currently guess will very likely at least include Tk, FOX, and 
GTK+ 2.0 by this time next year), do you happen to know off-hand what are 
regarded as the most serious Tk drawbacks for non-simple applications, in 
addition to not having as many (built-in, out of the box) widgets as most 
people nowadays seem to want and expect?
