It's easy to make the type `std:;foo()` when you meant `std::foo()`, which can
end up quietly doing the same thing if you happening to be using the namespace.
It's unlikely that a user really meant a labeled empty statement followed by an
unqualified function call, so it'd be good to throw up a warning and fixit
here.
