Hey all, I've just submitted an 8 patch set. I think I've managed to isolate each change. I'm currently ~65% of the way through rebuilding the following 178 packages in my local guix repository after the changes. No issues yet; If I encounter any I will update with a patch to fix it. Worth mentioning, this list of 178 was what `guix refresh --list-dependent python-flake8 python-pyflakes python-pycodestyle` said would trigger a rebuild of all 370 packages that depend on the above 3. Including the list of packages I am explicitly building here for transparency. -- Christopher Rodriguez
