[Tarantool-patches] [PATCH v1] Support to run tests with Python 3

[Alexander Turenko]

If you want my opinion, I think that the technical changes for support
Python 3 are enough. I don't mind style fixes, though.

I see, you answered the question, but I would highlight this part of the
discussion.

When you touch some code, you becomes its owner. Any questions like 'how
it supposed to work / how it works' are applicable.

If a developer would legally respond 'it is not my deal' on questions
regarding changed code, we would accumulate tech debts even faster than
now.

Of course, there is a line, where it starts to contradict with a common
sense, but in general a knowledge about the changed code is required to
actually change it.

I find this approach nice. It pushes me to know more and be more
confident about my patches.
