Comment (by pbruin):
Alternatively, instead of the `NotImplementedError`, we could temporarily
"implement" `_composition_()` as
{{{
return super(EllipticCurveIsogeny, self)._composition_(self, right,
homset)`
}}}
This just calls the method of the superclass and hence is practically the
same as deleting the method, but it makes it clearer where the "real"
`_composition_()` will have to be implemented.
