dart core functions treated as dynamic?

This line doesn't seem like it can possibly be right :)
https://github.com/dart-lang/dart-dev-compiler/blob/master/lib/typechecker.dart#L328

    if (type.isDynamic || type.isDartCoreFunction) {
      record(new DynamicInvoke(_rules, node));
    }

type.isDartCoreFunction <=> the type is "Function" in dart:core. E.g.,

void foo(Function f) {
f(27, "hello");
}

Aha! That makes more sense. I was confused by the API name, but yeah, the code makes sense if it's the special type Function. It really doesn't tell us more than dynamic.
