Sorry, I was unclear with the expression "be serializable": what I
really meant is not if it will merely implement java.io.Serializable,
rather if it will actually be serialized by an ObjectOutputStream
without any exception in all cases where a "regular" instance of the
SAM would have been serialized without exceptions, and deserialized in
the same conditions as well. That's imho a desirable feature to have,
but it places a possibly non-trivial burden on the implementation.
