I don't really want to hold up Sequence as the optimal implementation of a "coercing container", its just the only one that we have. IMHO: * adding elements should be allowed to coerce the universe of the container (which involves converting all elements to the new universe) * concatenating the containers should look for the common parent that the coercion model finds, and then convert all elements that aren't already in that parent (potentially converting the elements from both containers that are concatenated) -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
