[Python-checkins] python/dist/src/Lib sets.py,1.36,1.37

[gvanrossum@users.sourceforge.net]

Update of /cvsroot/python/python/dist/src/Lib
In directory sc8-pr-cvs1:/tmp/cvs-serv1406

Modified Files:
	sets.py 
Log Message:
Explicitly raise an exception in __cmp__ -- this clarifies that cmp()
is not supported on sets.  (Unfortunately, sorting a list of sets may
still return random results because it uses < exclusively, but for
sets that inly implements a partial ordering.  Oh well.)
