Dependency injection and factory?

The beauty of loose coupling is that we can constantly hide away the previous details .

The Factory pattern is a well known, documented, and used method. If you're that concerned about other devs not being up-to-speed, then put a link to wikipedia's factory pattern page in the (xml) documentation in the code.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
