FYI, there’s an updated discussion since the first link (only 6 months old, so relatively recent), with a prototype implementation: [[Prototype] Protocol-powered generic trimming, searching, splitting,](https://forums.swift.org/t/prototype-protocol-powered-generic-trimming-searching-splitting/29415)

It’s a good time to think about this. We recently added `RangeSet` and `DiscontiguousSlice`, and I think that might have reignited interest in predicate-matching (perhaps something like [this pitch](https://forums.swift.org/t/pitch-containmentset/11626)). If we can come up with a cohesive design for all of this, we should have a solid foundation for one-off patterns via regex literals.
