Right.
(actually, you could return any javascript object --anything that's
not a String, Number or Boolean--, it would work... until you try to
call a method or access a field, that would most likely not exist on
the given object).

Evaluating things from the debugger just doesn't work for
JavaScriptObject's (or any "native"/JSNI method), it's a known issue
that won't be fixed anytime soon:

Your code is OK, you just cannot use the debugger facilities...
