New description:
Several (maybe specialized) implementations of lazy lists exist. This meta
ticket can be considered closed when
* #15852: uncouple sequence from categories (was earlier: the `class
Sequence` has a parent from the category `Sets` implemented)
* `class Sequence`: maybe renaming to `FiniteSequence`
* #16137: extend lazy_list: lazy_list from various input data
* #19895: extent lazy_list: various improvements and generalizations, new
sublists
* #19896: implementation of `class InfiniteSequence`
* let both (`class Sequence`, `class InfiniteSequence`) use
`sage.misc.lazy_list`
* #15673: refactor code in `combinat.species.*stream` to use
`sage.misc.lazy_list`
* if obsolete close #6800
