Oh! I just realised that the source object will be passed through as 
the frist arg to the signal handler, even if you don't add it as an arg 
in the signal definition.

I'd still like to know if there's a workaround, since I'd also like to 
be able to do the following:

> class Primary(GObject):
>     __gsignals__ = { 'activate': (Object.SIGNAL_RUN_FIRST, None, 
(Secondary,)) }
>
> class Secondary(Object): pass

Without, counter intuitively, having to define Secondary first.

Thanks,
