This is implemented in Felix (more or less).

It only works if there are no 'cheats'.
In particular pointers to any static data
of the library, including char literals,
C++ virtual tables, RTTI, finalisers,
ordinary C functions, and who knows what else ..

The *only* thing protected is function closures :(
It's all very fragile. For Lua it won't be any better.

As usual, C is the big problem: it doesn't and never
will work with C, so why would it work in a system like
Lua (or Felix) with a C API?
