Comment (by mantepse):
> What operations are allowed on streams then? (I assume point-wise
addition; what do you need multiplication for?)
Well, I really want to keep them relatively general, mainly because I
won't gain anything by requiring certain operation. I do think that it
makes sense to require that the coefficients are from a (possibly
noncommutative) ring. I can't think of any applications where we do not
have this. I need the recognisable zero to be able to do the trick with
recursive definition.
> So your streams seem to be a more specialized than my sequences. In this
way, would it be an option for you that streams have sequences as a base
class?
Yes, certainly.
> Is a stream of you a Sage `Element`? (I would guess so).
Yes.
