Avoiding abstract

[Regan Heath]

Something else you might want to look at is how std.socket manages to return a TcpSocket or UdpSocket from it's base class Socket method 'accept'.

The trick/magic is in the accepting() method which the derived class overrides, internally it creates a new derived class (TcpSocket, UdpSocket) returning it as a base class (Socket) reference to the base class 'accept' call which then assigns the internal socket handle and returns it.

You could do something very similar.
