Hey, A new Oslo dependency is proposed here: https://review.openstack.org/16789 The library is called 'extras' and released its first version nearly a month ago: http://pypi.python.org/pypi/extras/0.0.1 https://github.com/testing-cabal/extras I don't forsee any objections apart from perhaps 'is a separate library for just try_import() really worth it?' I'm inclined to approve it, just want to give folks a chance to express an opinion. Cheers, Mark.
