You should be able to use Socket.setOption to set any socket 
option that is not specifically listed in std.socket.

The option enum value IP_ADD_MEMBERSHIP is available in the 
following lower-level modules:

std.c.linux.socket
std.c.osx.socket
std.c.windows.winsock

To access the correct enum value, import the required module for 
whichever OS you are using. You'll also have to do a cast of the 
value as follows: cast(SocketOption)IP_ADD_MEMBERSHIP

This solution is of course far from ideal, but it is a workable 
temporary solution until std.socket is improved.

I suggest that you file a bug report on this issue
