This is a little surprising.  So "from mod import *" really copies all of the
scalars into new variables in the local namespace.  The same is true with 
object pointers I suppose, but this is transparent as all the copies 
access the same object.

I always ASSumed that the two forms of import were equivalent, but that
one form did away with the need to be explicit about the namespace: mod.thing
Obviously this is far from the case.
