No changes to "global by default" and no checking are made to type annotations. The idea was to be able to convert any existing Lua code automatically and get it working as before like I did with some non trivial projects like:

- https://github.com/mingodad/CorsixTH-ljs - https://github.com/mingodad/ZeroBraneStudioLJS

But I implemented a warning/error for variable shadowing.
