I come from an academic background (sadly not in computer science) so I understand the need to promote the abstract advances that are being made here. However, I am a bit confused about the applicability of pypy. All the talk of backends, annotation object spaces etc etc may make some sense to really interested parties, but I would like to know what I can do in real terms with the new interpreters? The demo javascript stuff seems a bit fake since others have already done some work in that direction already using ordinary python. RPython may be larger or smaller than those subsets, but that's not clear. I would be interested to know if it's possible to point a tool at an existing python-2.4 module and wrap it into a much faster extension that can be used by my CPython stuff. I know there is preliminary work in that direction.
