> I think one thing that stalled adoption was the difficulty of migrating to Unicode string constants. This wasn't just down to the fact that Python 3 didn't support u"" (it was 3.3 that was added, for reference), but also down to the fact that much of the eco-system still supported RHEL5's default of Python 2.4 which meant `from __future__ import unicode_literals` wasn't an option (it is, almost certainly, a less good option, but it's in many ways good enough).
