Basically, I want to create Foo instances from pairs of numbers. This example does not compile unless Foo is adapted to fusion. I don't think this is a good idea, because from the point of view of user, the parser should create instances of Foo, and it's not really clear why parser should iterate over existing instances -- which is what it is trying to do.
