address.

@note Currently functors are compared by their address which,
unfortunately, doesn't work correctly if the same address is reused for
two different functor objects. Because of this, using Unbind() is not
recommended if there are multiple functors using the same @a eventType
and @a id and @a lastId as a wrong one could be unbound.
