How to define `:(==)` on user-defined types for `Set` operations

Thank you so much @mbauman! I guess what I really needed was confirmation that this was the right approach. Looking at that post again, I decided to use AutoHashEquals.jl and defined

using AutoHashEquals

@auto_hash_equals fields = (a,) struct MyType
    a::Int
    b::Int
end

And it’s working perfectly!
