-----------------------------+----------------------------------
Several (maybe specialized) implementations of lazy lists exist. This meta
ticket can be considered closed when
* the `class Sequence` has a parent from the category `Sets` implemented,
maybe with renaming to `FiniteSequence` (#15852)
* implementation of `class InfiniteSequence`
* let both use `sage.misc.lazy_list` (as default implementation? do
benchmark)
* refactor code in `combinat.species.*stream` to use `Sequence`
* how does the hypothetical `combinat.species.series.LazyPowerSeries`
(#6800) fit in?
Major improvements in `combinat.species.*stream` are planned in #15673.
