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. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue14288> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
