So, do we still have p5's 'want_array' (or whatever it was called)? That is, the predicate that tells the you whether the function is being called in item or list context? I know that the generalized 'want' function proved to be unworkable; but I'd expect p6 to at least be able to do everything that p5 can do; and that includes functions that are aware of whether they're being used as singular or plural. -- Jonathan "Dataweaver" Lang
