Tanner B 🦕🧁 on Nostr: npub1srcgh…xfms4 you used to not be able to do something like this: let type: ...
npub1srcgh979ychudzrha7asxa7kvennpghghzzadmv5gcunfw5p72qs6xfms4 (npub1src…fms4) you used to not be able to do something like this:
let type: Any.Type = …
let rawRepType = type as? RawRepresentable.Type
It would yell at you because RawRepresentable has "self or associated type constraints"
Well by adding `any P`, you can now interact with those types of existentials if their constraints don't matter to you at compile time!
