I'm committed a new version to show that this is not about by-

Utter type-safety is what Jason needs for something the size of

same type during each run.

Yup, I'm going direct to the DI use of the same concepts, trying to  
make a testcase close to Jason's real examples.

Jason, can you link to a component in your Svn that uses binding  
annotations already ?
