Exposes a TypeWrapper for the Python long integer type.
          Exposes the numeric
          type protocol of Python's built-in long
          type. The semantics of the constructors and member functions defined below
          can be fully understood by reading the TypeWrapper
          concept definition. Since long_
          is publicly derived from object, the public object interface applies to long_ instances as well.
        
namespace boost { namespace python { class long_ : public object { public: long_(); // new long_ template <class T> explicit long_(T const& rhs); template <class T, class U> long_(T const& rhs, U const& base); }; }}
namespace python = boost::python; // compute a factorial without overflowing python::long_ fact(long n) { if (n == 0) return python::long_(1); else return n * fact(n - 1); }
