// This test checks that all three steps of the instantiate-to-bound algorithm
// implementation, that is, substitution of variables in strongly connected
// components, substitution of dependencies in the acyclic remainder of the type
// variables graph, and using simply typed bounds, work together well on the
// same declaration.
