Great. For some reason, it didn't work in my initial tests; I guess I've 
been sloppy somewhere.

Any chance you make the --compiler=rebuild a default? Or is rebuild a 
separate product? (If so, that's not an attractive option.)

Essentially what you want is to make rdmd do the deed flag-free:

$ rdmd prog args

does whatever it takes to build prog.d (if necessary) and then runs it 
passing args. Each one necessary flag cuts your cut following in half. :o)
