I was a bit short yesterday, but it was already late. I meant

on_upperspin_valueChanged(self, value):

and the decorator saves the signature as an attribute of the function, for use
by connectSlotsByName.

Yes, that would be possible to, but the decorator approach is more explicit
Beautiful is better than ugly.
Explicit is better than implicit.
