new-style classes (the ones sticking around for python 3) are also instances.

    >>> isinstance(dict, type) and isinstance(dict, object)
    True

How can the interpreter know which interpretation to use?

When proposing a rule, remember to consider classes which are supposed
to have only a single instance (similar to a JSP).  Even if you
normally separate classes from instances, the line between "class" and
"the only instance of the class" can get kind of blurry.
