It's almost surprising rdmd is so immensely useful, eh :o).

BTW there was work on collecting dependencies while actually building. One nice
solution would be for dmd -v to generate a line at the end of imports to mean
"done". Then rdmd can run dmd concurrently and terminate if no need to generate
code.

I see it as the polar opposite. Improvements in rdmd clarify what sort of
primitives and interfaces we need for highly modular compilation.
