Research direction

Start with the thread in issue #1016, especially treeowl's linked code, then locate the existing Seq fold implementation. Done means implementing more efficient folds while accounting for the stated GADT portability concern; the payload names no test file.

Written by the indexing model from the issue text.

Description

discussion/rfc performance Seq

We can define folds for Seq more efficiently. See thread starting https://github.com/haskell/containers/issues/1016#issuecomment-2336465956 and in particular the code by treeowl in https://github.com/haskell/containers/issues/1016#issuecomment-2337033674

The catch is that we need GADTs, which is not portable.
