/// **What it does:** This lint detects giving a mutable reference to a function that only requires an immutable reference.
///
/// **Why is this bad?** The immutable reference rules out all other references to the value. Also the code misleads about the intent of the call site.
///
/// **Known problems:** None
///
/// **Example** `my_vec.push(&mut value)`
