Addendum: You can imagine my feature request like a `setImmediate` equivalent that I can call from Java.

My take on this: we should strive to be cross-compatible for as long as possible between Scala 2 and 3. I'd personally think that we should wait after the Scala...

I personally believe that a `Range` where `start` > `end` should be empty. In that case, your proposed test should fail. As for `inverse`, I'd probably try to get it...

@ashleymercer Since #358 cats-collection depends on Cats 2.4.0, so the missing instance is available.

That's great! I'd be happy to take a look at them.

Hi @sorenbug and thanks for your contribution! The current set/map files should really be prefixed with `Avl` (this includes the tests). As for your contribution, I recommend putting them into...

@sorenbug Thanks for following up! From my PoV, this implementation is ready for review (even without a HAMT implementation). Only thing missing now is tests for HashSet and HashMap. Ideally,...

Can we add a test for this?

That should basically be [ISet](https://github.com/typelevel/cats-collections/blob/master/core/src/main/scala/cats/collections/ISet.scala). Making it a functor [wouldn't work,](https://typelevel.org/blog/2014/06/22/mapping-sets.html) however.
