Use mixin naming to provide multiple signals, like so:

    class Foo {
        mixin Signal!(int, int) signalA;
        mixin Signal!(int, string) signalB;

Emit with signalA.emit(), connect with signalA.connect(), etc.  For the
latter question: I don't think so without redesigning the std.signals
module, which is probably worth filing an enhancement request for.
