// Elided lifetimes within the type of a const generic parameters is disallowed. This matches the
// behaviour of trait bounds where `fn foo<T: Ord<&u8>>() {}` is illegal. Though we could change
// elided lifetimes within the type of a const generic parameters to be 'static, like elided
// lifetimes within const/static items.
