LUA, worth it?

How about an opinion on LUA from /prog/? Don't believe it's been mentioned much around here.

Anything good able to be made with it?

I haven't played with it, but it looks very good. I had a look at the docs and this is what I can remember:

Win: dynamic typing, lexical scoping, everything is an object (including first-class functions), metatables, the forced tail call optimization if possible, small, fairly clean syntax

Fail: automagic conversion of strings and numbers (bound to cause problems), crappy regular expressions (absolutely incompatible with Perl's, besides much inferior)
