Detailed Description

An integer subclass that pickles / copies as None

This is used for non-slots classes with ``cache_hash=True``, to avoid
serializing a potentially (even likely) invalid hash value. Since `None`
is the default value for uncalculated hashes, whenever this is copied,
the copy's value for the hash should automatically reset.

See GH #613 for more details.
