I switch to lua branch then compiled it and try, seems some bugs there,
it can't run successfully:
-------------------cut--------------------
scheme@(guile-user)> ,L lua
Happy hacking with Lua!  To switch back, type `,L scheme'.
lua@(guile-user)> x=1
[enter]
[enter]
[enter]
^CWhile reading expression:
ERROR: User interrupt
lua@(guile-user)> 
-------------------end--------------------

And I checked the code, it doen't use Guile inner LALR parser.
Anybody point me out what is the suggested parser implementation? The
inner scheme-LALR(which contains GLR also) or manual parser generator?
Which is better for a practical multi-lang implementation?

And is there anyone ever evaluated the efficiency about the non-scheme
language implemented within Guile? 
Anyway, this wouldn't be a big problem, since Guile could be the future
dynamic language compiler collection, it could be optimized later.
