Summary: reverse copy of sequence returns None
Initial Comment:
I tried to get a reversed sequence and keep the
original, so I tried this:
>>> a=[1,2,3,4]
>>> b=(a[:]).reverse()
>>> b
>>> b=a[:]
>>> b.reverse()
>>> b
[4, 3, 2, 1]
>>>
I think this should be a bug. I tried to search this
bug but get no result. Hope my submit helps.
