// Test that we don't crash on computing js-interop classes when metadata
// constants contain implicit casts.
//
// We need the class hierarchy to perform the evaluation the implicit casts but
// we also change the class hierarchy when we discover that a class is a
// js-interop class. By mixing (valid) constants that contain implicit casts
// with the @JS annotations that define classes to be js-interop, triggering
// the use of the class hierarchy before all js-interop classes have been
// registered, this test causes dart2js to crash with an assertion failure.
