bool(obj) in Python has the following semantics: 1. if the object has __bool__() method, return its value 2. if the object has __len__() method, return its value 3. return True So for objects in QGIS API that implement __len__() method, we were getting unexpected behavior - for example, "if layer: ..." would evaluate as False in case the layer was empty, while the usual expectation is that any reference to an object that is not None should evaluate to True.
