Subject: Re: Optional static typing (or, What can Ruby 2.0 borrow from Boo?)

Hello David,


DGA> Koichi Sasada's talk on "YARV: Yet Another RubyVM" was interesting
DGA> in this regard:

No. Can you please give me the slide number of the slide that has
anything to do with the type system ?

They are still one generation back with this Bytecode engine (at least what
is visible from this presentation). Good modern LISP systems
(like Franz Lisp, or Allegro) or the expensive SmallTalk compilers
are at the moment state of the art and they use typing hints.

YARV is to optimize the really bad implementation of the control flow
in ruby programs. It does not touch the type system in any way.
