Type tuple of all constructors?

[Benjamin Thaut]

Is there a way to get a type tuple of all aviable constructors in a class?

class Test {
  public:
    this(Foo foo){
      m_foo = foo;
    }

    this(bool flop){
    }

    this(int x, int y){
    }
}

For this class I would expect something like ((Foo),(bool),(int,int))
