Oops. It slipped under the table. Here it is:

(*) A lot of languages which appear to be supported on .NET really
aren't, atleast not in their original form. Instead, a .NET version
of the language gets defined, which deviates in its semantics and
feature set from the original syntax. I would expect the same to be
the case for IronPython.

So far, I believe it is hard to tell, because IronPython is still
not complete. However, I firmly believe that you cannot make a
full Python implementation (i.e. with the language reference and
the portable standard libraries) on .NET which is also CLS
compliant. Maybe IronPython does not aim at being CLS compliant,
which might improve the chances that it is Python.

To see what I mean in other languages: Managed C++ is a language
different from C++, for example, the delete operator has a different
meaning in managed C++ than it has in standard C++. Likewise, J#
is a language different from Java. Essentially, I believe that
all these .NET languages are just different ways to write C#.
