As of last August, Rob Pike told me that google had no plans to move...

I take your point, but my reading is that the python world is still largely thinking of python 2.7 as being the version to target for the next couple of years.  I suppose that we'll all have to move to python3 eventually (I just wish it offered a larger improvement over python2), but not until all systems I deploy on have python3 as the at least almost-default python, with all the usual scientific packages such as numpy and scipy pre-installed.

Absolutely; that's why I haven't raised this point on the list before!  However, it does mean that scons doesn't have spare developer effort.  Being a volunteer project, if the active developers want to move to python3 that's going to happen and my desires won't change that.

I have looked at the code base, and it's not obvious for how an experienced C/C++/python programmer would understand enough to fix things like this without a significant learning curve.   Yes; this is an excuse.
