Comment (by vdelecroix):
Hello,
I have a question related to number fields (in particular #18226 and
#17830). I do want a direct coercion `number field -> RIF` based on the
(future) `_mpfr_` method of elements. Right now, the route is long as the
discoevery algorithm tells me that I need to do `number field -> RLF ->
RIF` (and actually there is `QQbar` hidden in the middle). I guess that
the proposition here would solve this issue! That would be fantastic.
Vincent
