Comment (by jdemeyer):
Replying to [comment:7 vbraun]:
> IMHO the coercion should be complex -> CDF -> CC and not complex -> CC
-> CDF.
Coercion goes both ways in this case (CDF -> CC and CC -> CDF), so the
result is the same really. Interestingly, this has the following
consequence:
{{{
sage: Sequence([CDF(1), CC(1)]).parent()
Category of sequences in Complex Double Field
sage: Sequence([CC(1), CDF(1)]).parent()
Category of sequences in Complex Field with 53 bits of precision
}}}
Let me know what you think, if you think the coercion should be added to
`ComplexDoubleField._coerce_map_from()`, I could do that.
