Two changes to from...import: 1) "from M import X" now works even if M is not a real module; it's basically a getattr() operation with AttributeError exceptions changed into ImportError. 2) "from M import *" now looks for M.__all__ to decide which names to import; if M.__all__ doesn't exist, it uses M.__dict__.keys() but filters out names starting with '_' as before. Whether or not __all__ exists, there's no restriction on the type of M.
