Lua is great, but it is missing a few things..
1. continue -- although Lua 5.2 adds goto, which does allow you to simulate this, but I don't see myself using goto..
2. no ++ or += etc. -- don't know why this isn't supported, shouldn't be too hard to add with custom pre-compiler
3. metaprogramming --Lua just doesn't have any good support for this, have to manipulate strings to accomplish anything
