@tmaier Looks like there's a small bit of formatting Rubocop doesn't like, happy to merge once that's fixed

Agree! This is definitely nice to have!

Should be ok to merge once rubocop is happy. 😊

I think i've fixed the style errors

@rarruda I merged your suggestion re. Array#to_h.

However, this is only supported for Ruby >= 2.6
Ruby 2.6 and below already hit EoL. 2.7 is about to hit EoL in April this year.
I can either revert this last commit or you could remove officially the support for EoL Ruby versions.
This change would be out of scope for this PR.
See https://www.ruby-lang.org/en/downloads/branches/

I should have tested the suggestion on 2.5 before mentioning it. Sorry about the extra work. My bad.

Let's revert and we can merge it as it was.

[tmaier]

@rarruda no worries. I removed that last commit.

@tmaier thanks for your contribution!
