I'm not saying we can't use the new syntax because of it. I'm saying it needs a bit \
more work, and before a 'stable' version is needed.
There is a solution out there. It's applied to QAIM and others.

If you do a stat call, or listEntry or <any of the others>...
Then you are supposed to connect to the result slot. For listEntry you are supposed \
to connect to the finished signal. Both of those are defined as: signals:
private:
AKA. Private signals.
I really don't see how you can work around this besides perhaps QSignalMapper, \
but that would be very odd as well. I'm really curious to see how that "bit \
of magic" is supposed to work. Do you have some links for me there?</pre> \
