A similar topic was recently discussed on the pypy-dev mailing list:

  http://codespeak.net/pipermail/pypy-dev/2010q3/006170.html


My interpretation is that the pypy devs are -0 on such a standardisation
effort, as it would give them less flexibility in moulding rpython for
their specific needs.  Adding features to rpython that make it better as
a general-purpose programming language could actually make it *worse* as
a specialised language for building pypy.

OTOH, there does seem to be a growing interest in using rpython as a
stand-alone language.  I've used it for some small projects and it
worked out great.

But the intersection of (people who want rpython as a general-purpose
language) and (people who have the ability to make that happen) seems to
be approximately zero at the moment...
