Re: LuaJIT FFI only bindings for glfw, OpenCL, OpenGL

Mike,

This is simply awesome!

And thanks everyone, I've learned a lot from the discussion!

I'm newbie lua user (used it long time ago, for external testing of
"C" library I had to support), and a friend of mine told me that my
code is not much lua looking :) I'll have to learn for example more
about metatables, (for example I don't know much about metatables).

I have some experience dealing with Common Lisp's CFFI, and LispWorks
FLI, and I find Mike's system very close to what I've used, if not
easier (declaring using the "C" way, rather than s-expressions would
be easier for randomly picked programmer).

Cheers,
Dimiter "malkia" Stanev.
