Are descriptors the most MISUNDERSTOOD part of Python?

Descriptors, in many conversations I've had with people, are typically considered one of the most difficult parts of Python. I would posit however that they're moreso misunderstood rather than difficult -- once you get your head around them, there's not much to remember! They're also an incredibly powerful and important concept, as huge swathes of the Python standard library is written using them, from properties to methods!
