I had 1 year of full-time experience with TCL, and I can basically summarize it in the same way as you: got a lot done with it, wasn't horrible, but don't miss it. In retrospect, I am kind of happy that somebody actually went and built TCL. "Everything is a string" is not really a sound PL paradigm, but someone needed to get stuff done, and it worked quite fine for that. It's super simple and super powerful, and beginners can be productive with it really quickly.
