Believe or not, I love ruby. :-p  I have always loved scripting
languages, and used tcl many times. (Unfortunately, I didn't code
anything complicated in Tk). Now I have found ruby, trying to code
programs with GUI, and the obvious GUI choce is Tk for me.

I am actually writing a network traffic meter, and if I write it only
with ruby/tk objects, it is painfully slow. Yes, I could write it in
tcl, but I want it to write in ruby, only (?) the canvas' object
handling needs some performance tuning, which I can easily code in tcl.

Anyway, the question above interests me irrespectively of my actual
problem.

Another task which needed to access tcl directly was require()ing tcl/tk
libraries. I am happy with using two (great) languages to help each
other; ruby is great in its well-designed OO support, tcl is
better/faster for me manipulating tk widgets.
