Hi Brian and thanks for the report!

I see. To me this looks like java-ts-mode is "correct", in that the
next step "outwards" is to the method start itself. The point is in
fact inside the method still, IIUC.

In this case I think python-mode is correct, becase the 'inner' function
is a sibling to the return statement, and it would make sense to go
directly to outer.

Yeah, I understand. Do you agree on my points above? I just want to
make the problem clear to me :-)
