One of my long-term goals for Idle is an extension that would run 
user-installed code analyzers over the contents of an edit window, with 
the output sent to an OutputWindow. Using the contents of the latter to 
mark things in the editor window is an interesting idea. That is already 
done for SyntaxErrors and traceback file:line references.
