Let's use them as a basis for a new 'python-updates' branch. Please also include this patch as it did not apply for me. I've pushed the other two to 'master' with slightly adjusted commit messages. You can open a new issue by sending a message to guix-patches@gnu.org, and send the patch series to [bug id]@debbugs.gnu.org. The initial email is typically a cover letter generated by git-format-patch(1). Python 3.6.2 is due in two weeks[0]. If we get 'core-updates' ready by then, we can start building 3.6 substitutes right away. :-) [0] https://www.python.org/dev/peps/pep-0494/#id2
