Deprecated: This module re-exports a limited subset of the class methods in the Foldable1 and Bifoldable1 classes, which are now located in the Data.Foldable1 and Data.Bifoldable1 modules in base-4.18. (On older versions of base, these can be found in the foldable1-classes-compat library.) Import from these modules instead.
