I didn't realize that this would come across as senseless bashing. My main complaints against TCL basically center around the everything-is-a-string mentality and the corresponding lack of type safety anywhere. A more minor objection is that I strongly dislike the syntax for numerous reasons, such as - Comments aren't like any other language and have numerous gotchas, e.g., you can't use mismatched {}s in a comment within a proc, - Whitespace is relevant in surprising ways, such as requiring Egyptian brackets for procs/ifs, and I constantly forget line continuations - Using foo for lvalues but $foo for rvalues, while sensible, is a constant source of typos... but, of course, you do get used to it. Mostly. But the comment thing really irks me. I will certainly agree that you can do worse. TCL is surely a fine alternative to awful shell languages (bash, C shell, etc.) But in the realm of dynamically typed scripting languages, I'd absolutely nominate Python or Ruby as a much more reasonable and sensible for your everyday programmer, and Lisp's S-expressions seem far more elegant if you insist on a unifying principle like everything-is-a-...
