Thank you for your time in entertaining my questions so far.

Functions are first-class objects.
Modules are first-class objects.
Classes are first-class objects.

There's even a ModuleType in 'types'.

>>> set( dir(type('None',(),{})) )- set( dir( ModuleType ) )
{'__module__', '__weakref__'}

How superficial are the differences?
