Epoll for D2

In D enums are kind of (but not really) strongly typed, so 
writing them all in UPPERCASE is often a bad practice. So 
something more similar to this seems nicer:

ev.events = EpollEvents.in | EpollEvents.hupxxxxx | 
EpollEvents.error;


> epoll.add(int file_descriptor, ev);

Is this correct D syntax?
