OK, despite all the other points you mentioned I attach here a file which
demonstrates the idea I'm talking about. In principle it only "frees"
the signal and forwards the call to QObject::connect, which is already
implemented by Oliver, so I assume it supports all features of Oliver's
code. No boilerplate code to write, only the 'new and ugly' connect
call.
