[boost] BIL and boost::any

Hello all,

I just realized that an empty BIL interface,

  BOOST_IDL_BEGIN(IAnything)
  BOOST_IDL_EMPTY(IAnything)

has some common ground with:

 boost::any

Where boost::any stores a copy of a value of practical any type for later 
extraction, IAnything can point to just about anything.

  void BoostAnyTest() {
    int x = 5;
    boost::any a = x;
    TEST(any_cast<int>(a) == 5);
  }

  void AnythingTest() {
    int x = 5;
    IAnything a = x;
    TEST(extract<int>(a) == 5);
  }

  void ObjectTests() {
    BoostAnyTest();
    AnythingTest();
  }

I just thought this could lead to some kind of connection between the 
libraries. It might be nice to see this in the boost::any namespace, i.e. a 
boost::any::any_ref.
