Greetings

Somebody please help me understand why we need the Tuple template in the following code. Does not __traits(getAttributes, foo.a) return a tuple? So what is the Tuple template doing here? Converting a tuple to a tuple?

Also where to learn more about tuples in D. Info in TDPL is sketchy.

Regards

template Tuple(T...) {

  alias T Tuple;

}

enum Bar;

class Foo {

  @Bar int a;

}

void main()

{

  Foo foo = new Foo;

  alias Tuple!(__traits(getAttributes, foo.a)) tp;

  pragma(msg, tp);

}
