[Baypiggies] how to programmatically invoke: from module import *

I end up writing something like this

     mod = __import__(module_name,fromlist=['*'])
     imported = dict((n,v) for n, v in vars(mod).items() if not  

This code has not considered __all__.

The fromlist=['*'] argument in __import__() is rather surprising. It  
doesn't really execute a "from module import *" as I expect. I still have  
to do filtering manually. All it does is a subtle difference in the module  
returned. In fact I can pass fromlist=['xxx'] and the result obtained  
seems to be the same.
