To be sure I understand -- is there anything wrong with writing

     scope auto f = new Foo(i)

... or, in general, using auto to infer the class being initiated?  I found myself
disliking the double writing of Foo, although I guess there could be a positive
side to it in ensuring that the class really is what it's meant to be.
