You may have good reasons to change the interface, but I'm somehow not yet convinced. Not that I really understand the impact (it's probably very low since that package is only used in rdeefx.spad and furthermore that constructor only seems to be an auxiliary package that is just needed for the Risch DE), but a change currently feels a bit odd to me. The reason for this is that the list of derivatives is something that I consider to be more or less constant, i.e. I'd expect just a few domains created with different lists of derivatives. Waldek, you are probably currently much more deeply into this integration business, maybe you can convince me that this "list of derivatives" is a parameter that is more frequently changing. Anyway, since that would be a rather local change, I don't currently have strong objection against it, but I would feel better if you give a more convincing argument. Ralf PS: What I don't really like is ld: List(F->F) It should rather be ld: List Derivation F with an appropriate "Derivation" type. -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
