Oh my goodness, thank you so much. I was planning to do this myself, to make contributions less noisy for others -- so happy to see you go for it.

there are some things which could be optimized, would you be open, to accept such a pull request?

Yes definitely. I haven't looked at the specific issues yet, so I may have some thoughts on perhaps ignoring some or resolving one way or another -- but opening up a PR would be a good first step.

I think Code Climate is wired up correctly now (it wasn't before), so we should be avoiding new ones coming in an get a nice, satisfying "Fixed N Issues" on the PR that addresses the existing ones :)

You are welcome :-) Happy that I can contribute something back to a tool I have used for such a long time.
I know these types of tasks, not really hard to do, but one cannot find time to do them.

Okay, I will look into that.
