"allowed anywhere, unlike in plain Lua" in the docs

These comments probably should be reworded — at the least. It looks like they're written from Metalua language's point of view, but this now is a generic Lua library...

I would expect the compiler to have three "modes" (at least logical) — lua 5.1, 5.2 and Metalua.

At least, when I use the compiler as a part of code linting tool, I'd expect it to catch the code that is invalid code for a given Lua dialect...

Indeed the parser factory ought to support 3 modes.
