I have mixed feelings about the equality trait in Rust. I have types where sometimes I want to compare by structure, and sometimes compare by reference. I can only implement Eq for one, so which do I pick?

If you have a value that can be any type (the 'top type'), what operations should your language support on that value? Equality is very common, but it's debatable. I increasingly feel that every value in a language should have some sort of debug print available.

Jest has this wonderful feature where it suggests other equality checks you might want to consider if your test fails. It's super helpful and a really nice touch.
