Comment (by pbruin):
I tried to (1) add a method `_floordiv_` to
`EuclideanDomains.ElementMethods`, and (2) make `DiscreteValuationRings` a
subcategory of `EuclideanDomains`. However, `f // g` then still complains
that the parents do not support this operator. If I understand correctly,
this is because `RingElement._floordiv_` comes before
`EuclideanDomains.ElementMethods._floordiv_` in the method resolution
order. We cannot remove the first one because it must be implemented in
`RingElement`, being a `cpdef` method.
Jeroen, do you (as the author of e.g. #2034) perhaps know a way around
this?
