- arrayvec.rs: Use concrete return types ([T], slice::Iter, slice::IterMut) instead of Self::Target/Self::IntoIter to avoid E0223 ambiguity introduced by the Receiver trait in Rust 1.87+ - char.rs: Explicitly import Result/Ok/Err from core for target_os=none where the standard prelude is not auto-injected
