developers are trying to come up with a solution. Python 3.4 solves some
existing problems, but this one remains. It's not just numpy here, it's
that python itself needs to provide some help.

If you think that anything in core Python will change so that you can mix
text and bytes as above then I think you are very much mistaken. If you're
referring to PEP 460/461 then you have misunderstood the purpose of those
PEPs. The authors and reviewers will carefully ensure that nothing changes
to make the above work the way that it did in 2.x.
