New Revision: 3332

Modified:
   pypy/trunk/src/pypy/appspace/sre_parse.py
Log:
This lets re.compile('a*') work on StdObjSpace.
It didn't work before. (Check yourself.)

It still does not work on TrivialObjSpace, but so what.

The problem was that StdObjSpace does not handle __(get|set|del)slice__ special
methods.

However, those special methods are declared deprecated since 2.0.
See Language Reference section 3.3.6.

Perhaps this should be fixed in CPython too?
