also see:

    http://www.python.org/doc/FAQ.html#4.47
    "4.47 How do I check if an object is an instance
    of a given class or of a subclass of it?"

which also points out that explicit class testing
might indicate bad design...  it's usually more
"pythonish" to just expect a valid object, and
trust the "user" to figure out that what the
AttributeError exceptions mean...
