"but it's not available on 3.5" also sounds like something that can be fixed now, not necessarily here

[a-detiste]

Yes ... but I'm really good at managing the Debian ecosystem and releases; not so much the native Python ecosystem (pip, tox etc...)

[alexmojaki]

Great! Is this ready to merge once the tests pass?

[a-detiste]

It is ready.

For what it's worth, a much dumber patch was temporarily used in Debian: https://sources.debian.org/src/python-asttokens/2.4.1-2/debian/patches/remove-six.patch/

The good things is that the CI suite of all reverse dependencies (the one using asttokens) passed fine.

-import six
+class six:
+     PY2 = False
+     PY3 = True
+     string_types = (str,)
