Andrei already provided one example, and another would be a proper unit type. e.g. void foo(int a) {} void bar (int b) { return foo(b); } - Is the suggestion to allow implicit conversion between (T) and T? This brings almost no benefit - (you save two keystrokes?) and adds a special case to the language. The added complexity really does not justify this.In fact, they don't need to unpack only for 1 element tuples, but this is the tricky case. Today, tuples auto unpack on function call for instance : auto t = tuple (1, 2); foo(t); // call foo(int, int)
Actually that's not the case. You need to write foo(t.expand); (and I think that's a good thing). Andrei
