You can put them in here:
I'm not sure about how to use custom ones without just copying them
in... need to research that.
There's no documentation about how to write custom ones here:
You can pass lib2to3 a package to try import fixers from. However I'm
not sure how to make that appear from the command line, other than
copying the fixer into place. I guess the numpy setup script could
copy the fixer into place.

something like numpy.compat.unicode_ ?

yeah I definitely would :) I don't have much time for the next week
or so though.
