Re: C under Lua

[LEGO <luis.ontanon@...>]

Two ways I see:
a) A bytecode to native (re)compiler with te help runtime lib
b) Lua2C

a) easier to implement, faster
b) harder and would probably lead to slower code but highly portable

BTW. Has somenone already written a LARL parser generator  for lua?
(something similar to C's or python's yacc or perl's yapp).
