The problem you had was about reassigning a name from a
module to an object, but it could have been any kind of
object - a variable, a function, another module, anything.
So really it had nothing to do with OO.

If  you do:

import sys as s
s = 42

you will get an error because you renamed sys to s then
used s as a local varuiable, thus overwriting (and thus losing)
the module reference. You need to ensure that your names
don't collide.
