Then you don't understand what I'm ranting about. It is certainly an  
improvement, but:

1) We don't have an infinity of programmer-hours. I'm saying that the time  
would likely be better spent at improving .di generation, which should  
have a much greater overall benefit per required work unit - and for all I  
can tell, you don't even want to seriously consider this option.
2) Once manually-maintained .di files are usable, they will be used as an  
excuse to shoo away people working on large projects (people complaining  
about compilation speed will be told to just manually write .di files for  
their 100KLoC projects).
