Update of /cvsroot/python/python/dist/src/Lib
In directory usw-pr-cvs1:/tmp/cvs-serv5565/python/Lib
Modified Files:
__future__.py
Log Message:
Expose the CO_xxx flags via the "new" module (re-solving a problem "the
right way"). Fiddle __future__.py to use them.
Jeremy's pyassem.py may also want to use them (by-hand duplication of
magic numbers is brittle), but leaving that to his judgment.
Beef up __future__'s test to verify the exported feature names appear
correct.
