Like the comment says, however, what if you have a local foo symbol defined? The compiler is going to complain, or silently choose one (I think with the new lookup rules, it would choose the local module’s name).

With Phobos, this isn’t strictly an issue, since we have no local symbols named std. But I could see lots of problems with other libraries.
