As far as I can tell in Signals2 to emit a signal you must have access to
the signal object, while synapse::emit takes an emitter object. For
example, with Synapse you could write:

QPushButton * b;
......
synapse::emit<button_clicked>(b);

(Of course emit<> has no use for the type of its emitter argument -- the
above would work just as well with a void pointer.)
