Check string indices when loading binary chunk
...
Lua is not religious about that, but it tries to avoid crashes when
loading binary chunks.

The main thread cannot be closed
...
No thread started with pcall (instead of resume) can be closed,
because coroutine.close would not respect the expected number of
results from the protected call.

A coroutine can close itself
...
A call to close itself will close all its to-be-closed variables and
return to the resume that (re)started the coroutine.

Loading a binary chunk should not break assertions
...
Although the execution of a bad binary chunk can crash the interpreter,
simply loading it should be safe.

Proper error message when jumping into 'global *'
...
A goto cannot jump into the scope of any variable declaration,
including 'global *'. To report the error, it needs a "name" for
the scope it is entering.
