The authors/maintainers of IronPython, Jython and PyPy all use
CPython's extensive suite of automated test ("unit tests" is really a
misnomer for the test suite) to check conformance. There are also
areas where the test suite is understood to verify CPython
implementation details which other implementations are free to ignore.
We don't really have a mechanism in place to prevent feature creep in
those versions; I trust their developers (even MS's IronPython, which
is spearheaded by a long-time Python developer). I also expect that
end users would give them a hard time for unnecessary deviations. Open
source helps here IMO.

Mail to security at python.org or Google for that exact term. The
committee mostly works behind the scenes, distributing patches to

Gee, I don't know. I always assumed Ruby and Perl would support it
too. Maybe it *is* unique though?

I find the purpose of educating Forrester a lot more important than
seeing "how we stack up". I'm getting tired of people proposing that
Python should grow feature X with no more justification than that Ruby
proposal isn't accepted.
