Comment:
Since certain methods are much more efficiently computed in certain
realizations,
the generic implementation just consists of converting to the favorable
realization, doing the computation there using a custom implementation,
and then converting back. But since converting is often expensive,
sometimes
a direct algorithm is given for more than one realization. This is the
case for :meth:has_descent.
