A type representing a closure expression is always bound to its "inferred" type based on the body, so contextual bindings just serve as a trigger to "resolve" a closure. Let's not attempt any subtype/supertype inference for a type variable representing a closure since if "direct" bindings have failed, it wouldn't be bound to such types regardless.
