Alexander Esgen 39db791bf3 Remove usage of head/tail (deprecated in GHC 9.8) ... Main occurrence is the operator tree code. This commit changes OpBranches [OpTree ty op] [op] to OpBranches (NonEmpty (OpTree ty op)) [op] such that the calls to `head`/`tail`/`last` can then be replaced by pattern matching on `:|` or by using the total replacements from `Data.List.NonEmpty`. Still, we need to call `NE.fromList` twice. `OverloadedLists` is only used in the tests; as it is otherwise too easy to accidentally write `[] :: NonEmpty a` without any warning. Alternatives to this commit are: - Just do the absolute minimal changes required to silence the warnings (ie basically inline `head`/`tail`). - Rewrite the operator tree code even further (maybe using more precise types) such that the `NE.fromList` are not necessary anymore.		2023-10-19 15:43:23 +02:00
