Thanks for the PR @sobolevn!

  • The tests only seem to cover cases where the code object is missing one of the position tables. Let's add a test like test_co_positions which uses the new positions API.
  • Let's also document the new API

Let's simply create an empty Positions() object here.

Thanks for the feedback! I've added docs about position field, but I didn't cover Positions namedtuple explicitly. I hope that reference to some "namedtuple" is good enough. But, I can fix it if needed 🙂

I have made the requested changes; please review again.

Thanks a lot, I think it looks good as is but let's clear the documentation a bit.
