Unless it is acceptable that it hangs: yes.

In what respect? The interact documentation says:

  "Closely emulate the interactive Python console."

So it is pretty clear to me that it is an infinite loop - just as the
interactive Python console.

They don't hide... When you import a module, two things happen:

1. the module is loaded and run
2. the resulting module object is put into sys.modules
3. the resulting module object is added to the namespace that
   executed the import statement. If you do it in the interactive
   prompt, it is added to globals(), which is __main__.__dict__.
[as any good list announced with two items, I have three of them]
