No Itisnt	a30c18c22a	add lua language implementation ... What is missing: + Functions: module, getfenv, setfenv, math.modf, table.sort + Parser: needs to be more flexible + Compiler: needs more extensive work to properly handle all possible cases of variable arguments, multiple returns, and loops + Language: Variable arguments and unpacking of multiple returns. (For example we need to be able to handle something as complex as print(unpack({...})), which is easy with Lua's explicit stack but will require lots of tree-il gymnastics, or perhaps modifications to better allow different calling conventions. (For instance -- how would we support Python or Ruby, where keyword arguments are gathered into a hashtable and passed as a single argument?) What is there: A fair shot at supporting Lua 5.1, not quite a drop-in replacement, but not far from that goal either.	2013-09-09 17:01:23 +01:00
