New description:
The current `sage.misc.lazy_list` only deals with infinite list built from
iterator.
In concrete situation (as in #15673) we want to create infinite list from
:
- iterator
- a function that given ``n`` computes the ``n``-th term (also called
closed form)
- a function which updates a buffer of already computed values (for
example : Newton iteration, relaxed multiplication, ...)
- an ultimatey periodic list (from a pre-period and a period)
- entries generated by functions (rational o.g.f. #15714, hypergeometric
e.g.f. part of #2516)
