This is a rather nice resource. Thank you for letting us know about it!
There has been an attempt to record different Python implementations on the
Python Wiki, and now that this is available again, I'd like to remind people
I know that this isn't quite the same thing as a page about compiler
technology, but there is a substantial overlap.

I think that given the scope of the projects listed, it shouldn't preclude
PyPy from being listed, really. After all, interoperability with CPython
extensions is something of a focus area for PyPy:
I don't have an agenda here - I don't use PyPy actively, my only involvement
with Shedskin (which is referenced and which can produce CPython extension
modules) is in packaging it for Debian, and although I do have a static
analysis library I see no pressing need to promote it extensively - but I
feel that when it comes to educational resources people should be a bit
careful about drawing boundaries that exclude things that would benefit
people substantially if they only knew about it.
My reason for speaking up about this is that I've had to tell a room full of
people who were told to use Cython, NumPy and even plain C to make their
Python programs faster that PyPy existed. (Of course, one can justify
ignoring the elephant in the room by claiming things like scientific users
rely on native libraries or CPython extensions - since "science" is a very
broad term, this obviously isn't universally true - but I think people should
be entitled to make their own minds up, and I was not completely certain that
everyone involved in the case in question was oblivious to PyPy's existence

There is also the python-static-type-checking Google Group:
If no-one beats me to it, I may post details of the site to that group because
it may well be of interest to the members. Thanks once again for bringing
such information together in one place!
