Such problems are called "whole program analysis", or "interprocedural 
analysis". There are a lot of cool things you can do with that, but of 
course they require 100% of the program text to be available to the 
compiler.

That isn't going to happen with D (even if all the D source were 
available, what about calling C binaries?). So we have to rely on other 
mechanisms.
