Hi,
A common source of confusion for newbies is the `AttributeError: NoneType has no attribute ...`
Also, one of my pet peeves for violating EAFP is the common `if something is not None:` ...
Both of these could be "fixed" by having a new exception (that subclasses AttributeError) e.g. `IsNoneError` (for the lack of better name) that is raised whenever `None`'s attributes are accessed.
Of course, one can already write `try: .. except AttributError` - but that catches also whenever something else than `None` is being accessed.
Do you guys think that this might be PEP-worthy idea?
