Fixes #555

Is there something wrong with GitHub Actions in this repo?

[moodmosaic]

@tomjaguarpaw, yes, I noticed too -- I am travelling today and I might not be able to look into it until tomorrow.

[moodmosaic]

@tomjaguarpaw, it's like they are all staying in queue forever. Unsure why though.

This is a textbook example of how to handle simplified subsumption compatibility issues. Thank you @tomjaguarpaw, and @HuwCampbell for the review. 👍

[tomjaguarpaw]

Thanks very much! Would you be able to make a release including this change in the 1.6 series so that I can make relude depend on in, and thereby keep relude building with Stackage LTS?

[tomjaguarpaw]

(In fact I think 1.6.0.1 would be a valid version bump, since no external behaviour changes.)

[moodmosaic]

@tomjaguarpaw, yes, that’s the plan. @BowTiedRadone works in #559 which will help. In the meantime we can release early this week. Hope it helps. Thank you!

@tomjaguarpaw, we never used the patch version. Wouldn’t 1.6.1 work?

[tomjaguarpaw]

Thanks, yes 1.6.1 would work.
