Example

PySide supports connecting signals by providing a keyword argument where the
name is the signal name and the argument itself is the callback object.

Currently there is a problem using this scheme to connect to signals that
expect arguments:

$ python-dbg test.py 
Traceback (most recent call last):
  File "test.py", line 10, in <module>
    obj = QSpinBox(valueChanged=callback)
AttributeError: 'valueChanged()' is not a Qt property or a signal

Example attached.

Added simple testcase for PySide in [1].

P3 as it isn't a crash and there are many possible workarounds.

this is the expected behavior for connection through constructor named
arguments. This is only valid for slots/signals without arguments.
