Please let's do it.

At first I was like 'why would I need that?'. But soon I ported 
all my (alive) projects to dub and never came back.

Since it can also generate projects for IDEs, it's also a great 
simplifier of projects. I've noted that it dramatically increased 
my likeliness to use and discover other's packages.
