2026-04-30 14:30:07 +0000 <haskellbridge> <thirdofmay18081814goya> it's also not clear it's possible for it to be anything else than a Fold since there's no obvious way to construct the covariant side of the profunctor

2026-04-30 14:15:46 +0000 <haskellbridge> <thirdofmay18081814goya> it's not just a cast into a fold + filter for more complicated structures, since we probably want to specify some notion of what gets preserved

2026-04-30 14:13:51 +0000 <haskellbridge> <thirdofmay18081814goya> what's the usual approach to filtering using optics? if I want to remove e.g. nodes from a tree or elements of a list matching some predicate
