Does Python really follow its philosophy of "Readability counts"?

Are you really saying that navigating through Python traceback and
frame objects is not equally black arcana?  Is there any hope of
debuggers for CPython programs that use those interfaces working in
Jython or PyPy?

Java, at least, has a well defined and documented debugging interface
that allows access to private and protected instance variables for
debugging purposes.  You can enable or disable that interface by
setting a runtime option when you start the JVM.
