Summary: fix inplace assignment for immutable sequences

Initial Comment:
Currently:

py> tup = ([], )
py> tup[0] += [1]
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
TypeError: object doesn't support item assignment
py> tup
([1],)

With this patch, no exception will be raised when the
item one wants to assign is already there in the tuple.
