One more thing: do you also know how to do the same for the cyclotomic
fields ? What I would need is something like
{{{
SetMorphism(
Hom(self, CyclotomicField(n), SetsWithPartialMaps()),
lambda elem: elem.to_cyclotomic_field()
).register_as_conversion()
}}}
The problem is that the parameter {{{n}}} is not determined a priori, and
I want the conversion to exist for any {{{n}}}.
