I think a fair summary is "go ahead, write what you want, it's OK".
In Claw.Sockets, type Socket_Type is non-abstract, with Open,
Read, Close, etc primitives appropriate for a blocking socket.
There's also
type Async_Socket_Type is abstract new Socket_Type with record ...
and various new primitives both abstract, eg,
procedure When_Readable(Socket : in out Async_Socket_Type) is abstract;
and non-abstract
procedure When_Connect(Socket : in out Async_Socket_Type);
The user is thus forced to supply a routine to handle incoming data
(When_Readable) but it's optional whether he supplies a non-default
routine to handle the initial connection event.
