modules with a hybrid implementation where the public Python module does 
a "from _native_module import *" to get the rest of the implementation. 
And even that is somewhat arguable.
To go back to Cesare's most recent example:
 t = ScrolledText.ScrolledText(master, width=60, height=37)
 t.insert(Tkinter.END, self.log.getText())
 t.configure(state=Tkinter.DISABLED)
 t.see(Tkinter.END)
 t.pack(fill=Tkinter.BOTH)
can look like:
 tk = Tkinter:
 st = ScrolledText.ScrolledText(master, width=60, height=37):
 st.insert(tk.END, self.log.getText())
 st.configure(state=tk.DISABLED)
 st.see(tk.END)
 st.pack(fill=tk.BOTH)
Cheers,
Nick.
