Yeah, you wrote a lot of thoughts and just to point some things that I
have been thinking:

- When you write an interface it would be nice to have a tool to create
stubs for a class. This is actually already implemented in eclipse for
example by providing fix tool which uses java's reflection api to find
out all needed methods. This is a direction like interface -> class.

- The other way around is also useful I think. In case that you were
proptotyping/hacking your code and then want it to stabilize more.
The programmer should be able to select methods and create an
interface for them, i.e., the direction would be like class -> interface.
