Replying to [comment:11 mstreng]:
> In general, even if there really is no preferred embedding of L into K,
then just choosing one will still lead to trouble, as you'll get non-
commuting diagrams of embeddings.
So may I paraphrase your proposal as follows:
If the element ''x'' to be converted is not in `QQ` and the fields have no
compatible embeddings, then `raise ValueError`?
