In addition to what Nicholas Wilson said, what you're doing here is the equivalent of writing `int;`. It doesn't make any sense as Cache!(...) is a type, and you are declaring a variable of that type... except you're not providing a variable name so the syntax is wrong. After you've fixed the other problem change it to this:
Cache!(BasicObject, string, lookupBasicObject) c;
