[New-bugs-announce] [issue16837] Number ABC can be instantiated

New submission from Alexander Belopolsky:

According to the reference manual, "None of the types defined in [numbers] module can be instantiated."  However,

>>> from numbers import *
>>> Number()
<numbers.Number object at 0x1005e5080>

This can probably be fixed by making Number.__hash__ an abstract method.
