The thing to emphasise here is that pickling an iterator is "destructive": afterwards the original iterator will be "empty".

I can't think of any other examples where pickling an object causes non-trivial mutation of that object.

Come to think of it, doesn't copy.copy() delegate to __reduce__()/__reduce_ex__().  It would be a bit surprising if copy.copy(myiterator) were to consume myiterator.  I expect copy.copy() to return an independent copy without mutating the original object.
