Research direction
Start with the ptr_arg lint and the supplied Rust reproducer, focusing on the IntoIterator use for &Vec. Run the reproducer and inspect the lint's existing tests or implementation to determine why this case is missed. Done means the lint reports the shown function without breaking related ptr_arg behavior.
