Yes, that similarity is not accidental :-)  It looks like it's "just"
a matter of hacking at lib_pypy/stackless.py to use ``transaction``.
But as I said it's possible that some changes to the API of
``transaction`` would be needed for an easier mapping.  Feel free to
try it out.

Maybe.  It's a language design question though, and based on future
technical work, so I'll not consider it for now.  The point of STM is
that it allows anything, and once we have a good implementation, we
can start tweaking other aspects (like the language) to improve
performance.


A bientôt,

Armin.
