[Python-checkins] CVS: python/dist/src/Lib/test test_inspect.py,1.4,1.5

[Tim Peters]

Update of /cvsroot/python/python/dist/src/Lib/test
In directory usw-pr-cvs1:/tmp/cvs-serv8019/python/Lib/test

Modified Files:
	test_inspect.py 
Log Message:
Add a function to compute a class's method resolution order.  This is
easy for 2.2 new-style classes, but trickier for classic classes, and
different approaches are needed "depending".  The function will allow
later code to treat all flavors of classes uniformly.
