I was quite surprised to read that you can't set a custom hasher in C++/Rust, and I even went and made sure that it's possible. But then I re-read your comment and realized you've meant that you can't do this in JS.

Oh you can, just implement toString and js will use it for hashing

  No it won't.

    Map, no. Plain object, yes.

      It doesn't "use `toString` for hashing", it just converts the key to a string. That is not the same (e.g. you can't recover the original key).
