[Python-checkins] CVS: python/dist/src/Lib/test test___future__.py,1.3,1.4

[Tim Peters]

Update of /cvsroot/python/python/dist/src/Lib/test
In directory usw-pr-cvs1:/tmp/cvs-serv5565/python/Lib/test

Modified Files:
	test___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.
