Following up: while sage's "RationalNumber" is indeed a numbers.Rational
according to "isinstance", it does not actually adhere to the stated API:
"numerator" and "denominator" are supposed to be properties, but in sage
they are methods. So even in places where we are trying to fit into
"Number
Taking a quick look at the relevant PEP
https://www.python.org/dev/peps/pep-3141/ or the documentation
https://docs.python.org/3/library/numbers.html#module-numbers (the PEP has
considerably more detail), I get the impression that our Integer and
Rational type could be incorporated in the hiera
I don't think there is any deep reason. Sage started much before the
existence of the numbers Python module.
Note that the concept of "Number" is not clearly stated in the library.
Does it include finite fields? padics? polynomials (these can be seen
as infinitesimal deformation of scalars)?

Hi, I was looking into typing a bit and realized that our number field
elements are not registered as numbers. So the following will not evaluate
to true:
sage: import numbers
sage: K. = QuadraticField(2)
sage: isinstance(a, numbers.Number)
Is there a reason, we do not register number fields in
