I've been implementing bytearray for IronPython and I noticed a couple of spots where the non-mutating methods of bytearray return self.
In 2.6 but not in 3.0 RC2: x = bytearray(b'abc') y = x.replace(b'abc', b'bar', 0) id(x) == id(y) In 2.6 and in 3.0 RC2: t = bytearray() for i in range(256): t.append(i) x = bytearray(b'') y = x.translate(t) id(x) == id(y) Given that bytearray always returns a new instance on all of the other methods shouldn't it return a new instance here as well? I'm just thinking someone could be planning on mutating the result here and not expecting their original bytearray to be mutated. _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
