///
- /// **Known problems:** None.
+ /// **Known problems:** Does not catch cases if the user binds `std::mem::drop`
+ /// to a different name and calls it that way.
///
/// **Example:**
///
/// ```rust
/// struct S;
/// unsafe {
- /// std::mem::ManuallyDrop::drop(std::mem::ManuallyDrop::new(S));
+ /// std::mem::ManuallyDrop::drop(&mut std::mem::ManuallyDrop::new(S));
/// }
