And can be added to the interface without breaking any existing code...

namespace boost {

  template<typename ValueType>
  ValueType acquire( const any & operand )  { return
any_cast<ValueType>(operand) ; }

  template<typename ValueType>
  ValueType * peek( any * operand )  { return any_cast<ValueType>(operand)
; }

  template<typename ValueType>
  const ValueType * peek( const any * operand )  { return
any_cast<ValueType>(operand) ; }

}

If Kevlin would agree with this idiom he could update the code and the
documentation quite easily.. (hint, hint)
