A general problem here is whether we can provide this infrastructure as 
a public API. If I have a class of mine and want to provide convenience 
for connecting to slots/callables, how do I do it without using private 
APIs? In Qt 4 days that was a simple:

   void foo(..., QObject *receiver, const char *slot);

But it's not so simple/possible any more with the PMF syntax.

Thanks,
