I second this. I've tried to create this C++ header feature a few 
months ago, but had to put it aside for lack of time. But the 
compiler frontend provides a lot of infrastructure that would 
need to be duplicated in any potential external tool that it's 
just going to be easier to have this as part of the compiler 
itself.

Besides, getting updated C++ headers for virtually free on each D 
compiler run can eliminate a whole host of potential bugs 
stemming from mismatched definitions because of incorrectly 
scripted build tooling. Multi-language/multi-compiler builds are 
unpleasant enough to automate as it is.
