// This tests that attempting to perform ModuleDeclarationInstantation a

// second time after a failure still fails. (It no longer stores and rethrows

// the same error; the spec changed in that regard and the implementation was

// updated in bug 1420420).

//

// The attempts fails becuase module 'a' is not available.

//

// This test exercises the path where the previously instantiated module is

// re-instantiated directly.
