-- | Strict data types to be used as accumulator for strict left folds and
-- scans. For more comprehensive strict data types see
-- https://hackage.haskell.org/package/strict-base-types . The names have been
-- suffixed by a prime so that programmers can easily distinguish the strict
-- versions from the lazy ones.
--
-- One major advantage of strict data structures as accumulators in folds and
-- scans is that it helps the compiler optimize the code much better by
-- unboxing. In a big tight loop the difference could be huge.
