Elixir doesn’t really have type dispatch though as it has no static type system, so I’m unsure what any kind of NewType could accomplish with this short of just `{:mytype, values}` or so as the purpose of NewType’s are to specify a unique set of functionality while hiding the original functionality of a specific type.
