That would pull it in here. What I mean is if:

module a: "weakly" imports module c
module b: imports module c


Module c is available, but:

dmd a.d c.d

explicitly uses module c, so it is pulled.

dmd a.d

only uses module a, because module c isn't used elsewhere and 
isn't explicitly pulled in.


dmd a.d b.d

does use module c, because it is required anyway by module b.
