Then I think you're suffering from an alas too common delusion. Static 
typing (at least declarative static typing) will only makes your system 
more complex. But if you want some help in managing complexity, you may 
want to look at interfaces systems (Zope3 interfaces or Peak's Protocol) 
and multidispatch (Peak's Protocol dispatch package).
