I see... Hmmm, I'm not in favour of maintaining two different parsers.
Maybe it would be better then to have a separate program that performs 
these checks. A bit like 'lint' does for C. But such a thing could be 
progammed relatively easy, I think, and why not in Lua itself?

On another note, I would love the function that luac uses
to dump lua functions and data to bytecode to become 
a library that can easily be integrated with the lua interpreter. 
On the fly compilation in the intepreter would be useful for 
AI applications or saving the complete Lua state in an easy way. 
I know that it's already possible to incorporate the compiler 
in the interpreter, but it is still not straightforward to do so. 
Having a "libluac" much like we have a "liblualib" would be
very nice indeed.
