In DList we have method remove, but I can't understand how this 
method works, I want write somethink like this:
 void unsubscribe(EventsSubscriber subscriber) {
     subscribers.remove(subscriber);

So I guess you would want something like

subscribers.remove!(a => a == subscriber));

which is the different definition of remove available here:

Just an FYI:
This didn't work as I expected -- the length of subscribers 
didn't change. What I needed here was
subscribers = subscribers.remove!(a => a == subscriber));

Otherwise this sort of behaviour resulted:
// code:
struct A {int i;}
A[] as = [A(1), A(2), A(3)];
writeln("as = ", as);
writeln(remove!(a => a == A(2))(as));
writeln("as = ", as);
writeln(remove!(a => a == A(3))(as));
writeln("as = ", as);

// output:
as = [A(1), A(2), A(3)]
[A(1), A(3)]
as = [A(1), A(3), A(3)]
[A(1)]
as = [A(1), A(3), A(3)]
