Reference equals doesn't make sense for a value object anyway.

  Unless you are using immutable objects. Then efficient equality check is referenceEquals() || deepEquals()

    1 is an immutable object, and in languages such as Java or C++ it's not a reference-type object. You meant heap-allocated immutable objects, like some kind of a Haskell list, or maybe small stack-allocated immutable objects, like a tuple.

    That should be in the guts of the implementation of == for value types, not something exposed outside of it.
    • quickthrower2 4y ago
      Yes I agree, in Haskell it is derived, for example.
