Right, which is why I suggest only issuing the shadowing error if the member
doing the shadowing is actually used inside the with{} block.

It's very dangerous the way it is.

Adding a member to an object in file A.d could cause behavior of code in B.d to
change, without creating any sort of compiler errors.  That seems to be the
kind of hijacking effect that usually gets you up in arms, but here you don't
seem so concerned about it for some reason.
