Re: C upvalue cleanup not being called

Thanks,

It's my mistake for sure. I copied the code from lua-cjson and the 
finalizer gets called in that code in 5.1 
https://github.com/mpx/lua-cjson/blob/master/lua_cjson.c.

I know it's something stupid but I don't know the C API well enough to 
fix it. The full code is here http://hastebin.com/likikexinu.coffee.
