[IPython-dev] PyQt5?

You are right that PyQt5 is not really on our radar. The Qt code in IPython
is not getting much attention at this point - it basically works, and we do
not have any immediate plans to do more interesting things with it. I think
it is too late to get PyQt5 support into IPython 2.0, but I think it is
quite reasonable for 3.0.

We already have a compatibility shim in IPython.external.qt, so that is
where I would start to look for dealing with whatever changes PyQt5 makes.
