What do you dislike about Tcl? I always kinda liked it.

The implementation is pretty good, but 1-based arrays are pretty evil. I don't know if I like the way arrays & tables are conflated either: part of me thinks it's clever, and part thinks that it's too clever by half.

It's also pretty verbose.

Something I like about both Tcl & Lisp is that they have a good built-in messaging format (Tcl object notation in the former, and S-expressions in the latter). Lua doesn't really have something similar, which is IMHO unfortunate.
