Exactly right.  Those represent the RIGHT way to do things.   "import
wx" brings in exactly one name into my global namespace.  Until very
recently, most wxPython applications started out
    from wx import *
which brought in THOUSANDS of new names directly into my global namespace.

With the new method, I say:
    class MyApplication( wx.App ):
With the old method, I said:
    class MyApplication( wxApp ):

Now, the naming convention gave you a very good hint, but you could not
grep for wxApp and know with certainty where it came from.  With the new
method, I can search for wx and find its import.
