I don't understand your comment. Maybe I'm missing something?
That's exactly what DSF is isn't it?
We just choose to name the method 'open' instead of 'get'.
And the static `DSF of(DSF)` method is simply there to provide
a type witness and avoid a cast (you get a compilation error
otherwise).

In other words - we could possibly replace
   { "..", DSF.of(() -> new DatagramSocket()) }
with
   { "..", (DSF)() -> new DatagramSocket() }
but
   { "..", () -> new DatagramSocket() }
will never compile.

best regards,
