Summary: x!=y and [x]==[y] (!)

Initial Comment:
Easy to obtain the weird behavior in the summary (in 2.5rc1 and earlier):

>>> inf=1e9999
>>> x = y = inf/inf
>>> x!=y and [x]==[y]
True

I propose to fix it by ensuring that lists (and tuples etc) compare their 
items with exactly the same logic as the == and != operators use.
