(You can always turn on the >GC in ATS and code in an OCaml-like fashion if you wish.) Thank you, that sounds very encouraging. So are you saying that if you turn on the GC in ATS, the performance is not so different? And yes, I misspelled the name, the correct one is ATS, I am sorry. > Kevin Cheung said: > Unfortunately, I don't have much to say about AST at the moment.

However HLVM+Ocaml is probably still years away, while ATS can be used right now.
