Hello aJ,
You sound angry that your feature is not a fit for my development process.
I think the frustration here is that you seem to be saying that you can't do something in D that you want to do but we have yet to figure out what it is. Every thing I have seen you ask for is already possible with D as it is now (including hand writing both the header and implementation in different files with all the potential for errors and duplication of work that D tries avoid).
"jump in and start coding algorithms" is not an acceptable development method in my book.
In my experience, where you can't just start writing code, you can't just start writing headers either. I'd start on a white board or word and once stuff is designed there, I'd implement stubs with enough comment to know what they are supposed to do. In this mode, the header files would just be busy work.
