Based on #31 to avoid conflicts.

Nice 👍

The base branch was changed.

I kind of disagree with this. it forces a lot of empty lines into code and can actually reduce the readability?

Agree after seeing this in action 💔

[nickvergessen]

In Talk it would add 997 new lines 😱

For personally not, as I always write my code with these newlines, but sure don't need to force everyone to have this style.
There seemed to be quite some agreement on this though, as the 3 needed reviews came in very fast and without any objections.
