A compatibility package for the `Foldable1` and `Bifoldable1` type classes,
which were introduced in `base-4.18.0.0` (GHC 9.6.1). For more information, see
[this Core Libraries Committee
proposal](https://github.com/haskell/core-libraries-committee/issues/9).

`Foldable1` and `Bifoldable1` classify non-empty data structures that can be
folded to a summary value.
