object variants are more flexible than enum types so what you see as a limitation others don't.

  No, I want first class algebraic datatypes that don't make easy things hard i.e. https://forum.nim-lang.org/t/904 https://forum.nim-lang.org/t/904 vs `#[derive(Eq)]`

    Libraries exist: https://github.com/haxscramper/nimtraits https://github.com/haxscramper/nimtraits https://github.com/andreaferretti/patty https://github.com/andreaferretti/patty https://github.com/alaviss/union https://github.com/alaviss/union Again we are not new to this problem and already offer alternatives.

      This is something that should be in the core language, not in a deprecated library

        Mind explaining why algebraic types are better? than cased objects and why a limitation in the fields iterator, that prevents `==` to be automatically lifted, is connected to that?
