Well, as the man who claimed to take up guile-lua, I shamed. :-(
Though we have guile-lua, it can't work successfully.
The problem of current guile-lua is that the original author didn't use
Guile inner LALR which ludo suggested to me, but a manual parser. So
it's a little hard for me to read & learn them all then fix the bug in a
short time.
Besides, I'm trying our brand new PEG, which is very cool.
And the dilemma comes to me: now that original guile-lua can't work, and
Guile suggest LALR/PEG to handle front-end, should I rewrite guile-lua?
Even keep it was, I have to spend more time to learn the original code,
which seems no efficient.

However, lua-bytecode->guile-bytecode or lua-ast->guile-tree-il maybe
another way to go, but no my aim.
