// This test demonstrates a limitation of the trait solver.
// Basically, one might think that `T` was covered by the projection since the
// latter appears to normalize to a local type. However, since we instantiate the
// constituent types of the self type of impls with fresh infer vars and try to
// normalize them during orphan checking, we wind up trying to normalize a
// projection whose self type is an infer var which unconditionally fails due to
// ambiguity.
