Hello, On a PyPy I translated this morning, I'm seeing weird behavior importing a module that messes with sys.modules (not a nice thing to do, but I would still expect it to work): exarkun@boson:/tmp$ ls -lR trickypackage/ trickypackage/: total 4 -rw-r--r-- 1 exarkun exarkun 61 2010-01-09 11:39 foo.py -rw-r--r-- 1 exarkun exarkun 0 2010-01-09 11:40 __init__.py exarkun@boson:/tmp$ cat trickypackage/foo.py import sys sys.modules['trickypackage.foo'] = "Hello, world" exarkun@boson:/tmp$ python Python 2.6.4 (r264:75706, Dec 7 2009, 18:45:15) [GCC 4.4.1] on linux2 Type "help", "copyright", "credits" or "license" for more information.

from trickypackage import foo foo 'Hello, world'

exarkun@boson:/tmp$ ~/Projects/pypy/trunk/pypy/translator/goal/pypy-c-70469 Python 2.5.2 (70469, Jan 09 2010, 15:24:34) [PyPy 1.1.0] on linux2 Type "help", "copyright", "credits" or "license" for more information. And now for something completely different: ``PyPy doesn't change the fundamental physics constants''

...

from trickypackage import foo foo <module 'trickypackage.foo' from '/tmp/trickypackage/foo.py'>

Anyone have any idea why this might happen? The real problem this is causing for me is with the twisted.internet.reactor module, of course. Jean-Paul
