I agree that it's on the library proposer to convince everybody here of 
the value add of the technique, and then his proposed solution.

Vocab libraries often struggle with communication, because what they 
solve is so fundamental. It's a steep hill to climb, but necessary to 
get such a library into Boost.

Kris I don't suppose you can rustle of somebody who is using DI in 
production and would be willing to either open source that code, or come 
here to describe how DI solved a pain point for them?
