lazy_findall(?Templ, :Goal, -List) is det

lazy_findall(+ChunkSize, ?Templ, :Goal, -List) is det

True when List is a lazy list containing the instantiations for Template for each answer of Goal. Goal is executed in an engine (see engine_create/3).

bug: - Engines are reclaimed by atom garbage collection. As they can be quite expensive, a large amount of resources may be waiting for collection. If the list is fully materialized only the dead engine remains, which is fairly cheap.
