It's odd that some packages already have python-3.6 (e.g. portage), and some don't have it (e.g. gentoolkit, smart-live-rebuild).
=app-misc/pax-utils-1.2.2 I try to use lddtree with python3.6 selected and that is what I get: Traceback (most recent call last): File "/usr/bin/lddtree", line 52, in <module> from elftools.elf.elffile import ELFFile ModuleNotFoundError: No module named 'elftools' =dev-python/pyelftools-0.24 PYTHON_TARGETS="python2_7 python3_4 python3_5") Should a python3_6 target, be added?
This needs to be done per package, hence, feel free to open bug reports (or, better, github pull requests) for the packages you have tested to work with python 3.6
