LOL, I've always wondered why TCL didn't become more popular since it has a lot of advantages, on paper. The one thing that really turned me off of it was the way it looked, really butt ugly.
oh, its hideous. Especially when hardware design engineers write it. No tests, no real comments, just code that didn't work commented out. For all of the flack PHP receives, TCL is a hammer with the steel claw removed and replaced with a picture of a butterfly.
Yeah, I'm a hardware engineer, and I've come across code like that! But it's not Tcl's fault that hardware engineers can't write code, or even comments to go with the code.
I guess beauty is in the eye in the beholder. I like the syntax, but you're right that a lot are put off by what the syntax looks. If you get past that however, it's a very, very nice bit of kit.
