In order to make this kind of argument work, you need evidence. The 
sensor example is weak because (a) it comes with a rich context that is 
only vaguely explained; (b) it is not shown translated in current D; (c) 
it comes from private correspondence - at best it should be from a 
visible project. As of right now, the argument about application code 
being more helped than library code is purely speculative.

That's why I also suggest looking at dub and github, which contain a 
good amount of D application code. You'd make a solid point if you 
showed how a few of those projects can be improved by the use of the 
proposed feature.
