> {{LazyList}} supports a {{Factory}} for creating new elements on first
> access. Since a {{Factory}} does not take any arguments, those elements can
> not depend on any input values.
> A possible use case is a list of objects from a database, fetched by their
> id. If an element at a specific position is requested, it is retrieved from
> the database lazily. This would require support of a {{Transformer}} (from id
> to database object).
