So emit and connect would take just a string as the signal or slot
argument?

I think making them optional is better than dropping, from what I've
read here so far there are people that use documentation for PyQt3 as
basis for learning PyQt4 and this is a major change.

Also then you'd have to change all examples, that may be accomplished by
a simples regexp-search&replace depending on the way it works without
them. The same for all programs out there that already use PyQt4.

So my opinion: Make em optional but clearly document the "other" way and
it's benefits and downsides. Maybe even convert some or all examples to
work without SIGNAL/SLOT.
