I do not think that metalua fits better than XTC Rats! + Scala for compiler
I checked metalua in 2007 (version 0.2 alpha, if I recall it right) before I
began my work - and didn't find anything vital for my purposes. Front-end was
hand-written, pattern-matching algorithm was naive.
Most of all I disliked compilation to bytecode only - because of the lack of
compatibilty with 5.0.x and LuaPlus (compatibility was essential for me) and
tricky debugging (AST dump only). Also, I didn't like that even bytecode had
BTW, why metalua compiles to bytecode - because of goto?
