Simple implementation Serializers which allows registration of serializers based on raw (type erased class). It can work well for basic bean and scalar type serializers, but is not a good fit for handling generic types (like Maps and Collections).

Type registrations are assumed to be general; meaning that registration of serializer for a super type will also be used for handling subtypes, unless an exact match is found first. As an example, handler for CharSequence would also be used serializing StringBuilder instances, unless a direct mapping was found.
