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.
