Does rdmd handle cases where the dependencies have dependencies? Suppose app.d imports foo.d which imports bar.d dmd app.d can't find module in foo.d retry: dmd app.d foo.d can't find module bar.d try again: dmd app.d foo.d bar.d success. Is it possible to cut out any one of those steps without caching that third dmd line? Until you try to compile foo.d, it can't know bar.d is required...
