#498 introduces a very weird behavior: If I have: * msgpack==1.0.3 ``` >>> import msgpack >>> msgpack.version (1, 0, 3) ``` If I have: * msgpack==1.0.4 ``` >>> import msgpack >>> msgpack.version Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: module 'msgpack' has no attribute 'version' ``` but if I have: * msgpack==1.0.4 * msgpack-python==0.5.6 ``` >>> import msgpack >>> msgpack.version (1, 0, 4) ```
