Nick's right; 0 fails on an import * to pull anything in of interest.

but if the imported module has

try: import blocked_module except ImportError: do_something_important()

then import_fresh_module() will create a broken module with do_something_important() not executed.

And as I said on python-checkins -- you can ignore that email, Alexander

Too late. I already replied. :-)

-- there is a historical reason because in Python 2 if you tried an implicit relative import a value of None met to do an absolute import. This doesn't have that effect in py3k as explicit relative imports are the only way to do relative imports (and luckily importlib does the proper thing for this as well =).

Is there a problem with this change for 3.x?
