I would GUESS that their enhancements involved semantic restrictions or
app-specific tunings. E.g., limiting table keys to strings, getting rid
of metatables, memory pooling for a common object size...
I'm just guessing, of course, but I wouldn't get my hopes up about
their changes feeding back into Official Lua.
