[PyQt] Unable to weakreference pyqtBoundSignal

[Kyle Altendorf]

TypeError: cannot create weak reference to 
'PyQt5.QtCore.pyqtBoundSignal' object

Are pyqtBoundSignals intentionally not weak referenceable?  If not, 
could it be?

Example and output:

Since I already had it open:
     https://docs.python.org/3/extending/newtypes.html#weakref-support
