minor python 2.2 wart?

[Brian Kelley]

The following code snippet compiles when it probably shouldn't:

import StringIO

class Foo(StringIO):
     pass

f = Foo()

Note that it doesn't run :)

Should the compiler be smart enough to know a module from a class? 
Deriving a class from a builtin function doesn't compile:

class Foo(map):
      pass

For my own edification, is there any reason why this should happen or 
should I send it to the bug tracker?
