I do the same thing with a twist [0], since I'm not very fond of some of Lua's design choices. Lack of a decent type system, the table mess, etc. And I think Forth and Lisp make better glue languages.

Can't stop smiling these days when I see people fighting over which language will rule them all. I spent tens of years searching for that language myself. Time I would rather have spent solving real problems using the best tools.
