LUA Implementation Limitations & Notes

Underworld's LUA VM is a modified version of the 2009 lufacode project. It implements a small subset of the LUA 5.1 specification.

There's a lot of caveats to be aware of when writing LUA code for it:

• Most LUA library functions are not implemented, including pairs. I've implemented a quick table.keys functionas a workaround (see the clone utility function that uses it)
