Ah, thanks:  I misunderstood the thread topic (sorry).  ;-)

Agree that I don't have a use case for the "old" connect syntax anymore
(fine with me to deprecate it).  I prefer catching errors at compile-time
with the new syntax.

I've "overheard" some discussions in other circles about ditching all of
signal/slot in favor of lambdas, and apologies for dragging that into the
discussion.  It's something I've been thinking about a lot ...   ;-)
