From what I understand, the new approach makes use of bundles and is therefore much cleaner and more intuitive. That's of course very good. OTOH, I can easily think of further goodies that gretl might get in the future and which would make a different interface/approach even more convenient. (To be concrete, having named function arguments as opposed to only positional arguments would sure inspire changes for many packages.) Do we want to change the Kalman interface (or other stuff) again once that gets added to gretl? As I said, I'm not sure what the decision should be in this case. But I'd say that gretl/hansl is old enough by now to make some fundamental design decisions now and then stick to them. Right now I only have that example with named arguments again, but I think it's a good example: Do we ever want them, then why not now? (I'm talking about making the decision, I know that the implementation takes time and work and cannot happen now now now.) I can also live with the decision that it's not worth the effort, but then I wouldn't want to see them next year and somebody saying we have to change the Kalman interface again because of that. cheers, sven
