Right, this is what twisted does and it makes it very hard to see what 
components are available and where they come from. It also makes it 
practically impossible to override components without getting into the 
ordering mess you mentioned.

I also note that the code browser now supports looking at ZCML files. Not only 
will it highlight the code for you, but also provide links to specified 
components. I think this might be very helpful for people to discover the 
system. ZCML is a great way of getting a quick overview on how things hang 
together.
