    18 also add (from https://trac.sagemath.org/ticket/30061#comment:44) `EuclideanSpace` (implementing the distance function by means of the Cartesian chart) and possibly other manifold classes.
     22On this ticket, we add (from https://trac.sagemath.org/ticket/30061#comment:44) `EuclideanSpace` (implementing the distance function by means of the Cartesian chart) to the category.
     23
     24To do this, we rename the `MetricSpaces` parent method `metric` to `metric_function`.
     25
     26The other examples from above will be taken care of in #30092 (which adds inner product spaces) and #30219 (real embedded number fields).
