Example:

------------------
module a;

class foo {
}
------------------
module b;

import a;

class fool {
}

void bar( ) {
     auto f = new foo( ); // Oh noes, I meant fool, not foo!
}
------------------

As you can see, this is perfectly possible with things other than global
variables. One could even imagine mistyping a module name and still getting
a program that compiles. Now how does C# make that impossible?
