+used for every @code{Foreign.Storable.Storable} type.  See also package with a
+similar intention at http://hackage.haskell.org/package/vector.
+
+We do not provide advanced fusion optimization, since especially for lazy
+vectors this would either be incorrect or not applicable.  However we provide
+fusion with lazy lists in the package
