Ticket #16507 should solve this (at least to some extent) in situations where there is a coercion B -> A instead of A -> B. (Here B is the object resulting from a functorial construction applied to A; this can be used if B is a submodule of A, for example.) This won't address things like (base ring, cusp forms) -> (modular forms), though. Peter -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
