That reminds me of something; in PEP 333 I proposed use of a 'close()' 
attribute in anticipation of PEP 325, so that web applications implemented 
as generators could take advantage of resource cleanup.  Is there any 
chance that as part of PEP 340, 'close()' could translate to the same as 
'__exit__(StopIteration)'?  If not, modifying PEP 333 to support '__exit__' 
is going to be a bit of a pain, especially since there's code in the field 
now with that assumption.
