+- **Trait methods with a wildcard type**: ``<_ as Trait>::method``, for example ``<_ as core::clone::Clone>::clone``. This form matches any type that implements the trait and is useful for modeling broadly applicable trait methods. For a type that has a specific model (<Type as Trait>::method), that model will take precedence over the trait model.
