Not to hijack the OP's thread, but a follow-up question:

what speed-up can realistically be expected? I 've seen Koichi's slides
and they look impressive but if I am not mistaken the optimizations
looked to be concerned with basic math operations and so on. what about
function calls / blocks / object instantiations / hash and array
implementation / .... ? Is YARV going to muscle those around as well,
or not really?
if so (or if not), what performance improvements would be within reach?
