Are the inter-package dependencies handled correctly? It's hard 
to say looking at the diff, but I don't see where it's done.

With the "compile everything at once" model it's not an issue; 
everything is getting recompiled anyway. With per-package... if 
foo/toto.d gets changed and bar/tata.d has an "import foo.toto;" 
in it, then both foo and bar packages need to get recompiled.

Or is this change recompiling everything all of the time but just 
happens to do it a package at a time?
