/// This can lead to confusing error messages at best and to unexpected behavior at worst.
///
/// Note that this will not warn about wildcard imports from modules named `prelude`; many
/// crates (including the standard library) provide modules named "prelude" specifically
/// designed for wildcard import.
///
/// **Known problems:** If macros are imported through the wildcard, this macro is not included
/// by the suggestion and has to be added by hand.
