Swift: Any way to extract the bound "self" from a closure?

I discovered a neat property of Swift: Anywhere I can pass a closure, I can also pass a object method (of matching type), and if I reference it from an instance, it captures that instance for the call:

class
Foo
{
    func actOnFoo(inValue: Int)
    {
    }
}

func
neato()
{
    var foo: Foo = Foo();
    doSomething(foo.actOnFoo);
}

func
doSomething(inFunc: (Int) -> ())
{
}

Inside doSomething(), is it possible to get at inFunc's "self" (in this case, it would be foo)?
