// Test to see if a Dart class name is confused with dispatch tag.  Both class A
// and class Z have a JavaScript constructor named "A".  The dynamic native
// class dispatch hook on Object.prototype should avoid patching the Dart class
// A.  This could be done by renaming the Dart constructor or by being able to
// check that objects are Dart classes.
