[IronPython] PyPy meets Jython (could meet IronPython too?)

The Jython guys are joining forces with the PyPy guys to collaborate on 
CPython compatibility for alternative Python platforms.


Suggestions that are relevant to IronPython include:

# ctypes - try to create _rawffi module in Java for Jython, which will 
enable Jython to reuse our existing ctypes implementation (and have PyPy 
use the Jython-rawffi for its own for PyPy.JVM)

# generally see to share work / (continue) collaborate regarding 
extension modules

# collaborate on testing framework / benchmarking, have a common site to 
show test results

# come up with a set of "pure Python language" tests, which would gather 
and refactor tests from CPython, PyPy and Jython.

It would be great to see IronPython participate. A common set of 
language tests, written in pure Python, could greatly benefit IronPython.

Additionally, an implementation of ctypes for IronPython (using the .NET 
FFI and building on the PyPy work) would enable IronPython to use any of 
the extension modules developed for Python by PyPy. More and more 
standard library modules are implemented using ctypes now.

All the best,

Michael Foord
