How about Go's... error on unused imports?

[Leandro Lucarella]

I'm sorry to bring up another "How about Go's ..." topic, but I think this
feature is very in sync with D and it should be really easy to implement.

Go issues an error if you have an import that's never used, to avoid
unnecessary dependencies.

Do you see any reasons not to do that? I think it happens very often to
stop using some import and never notice it.
