I like c++ and boost£¬but write namespace is a boring work for brace-matching.

So I write a small util with boost.preprocessor, like below:

#ifndef BOOST_NAMESPACE_UTILITY_HPP_
#define BOOST_NAMESPACE_UTILITY_HPP_

#include <boost/preprocessor/seq/for_each.hpp>

#define _PP_NS_BEGIN_FUNC(r,data,elem)  namespace elem {
#define _PP_NS_END_FUNC(r,data,elem)  }

#define BOOST_BEGIN_NAMESPACE(SEQ)  \
        BOOST_PP_SEQ_FOR_EACH(_PP_NS_BEGIN_FUNC, ~, SEQ)

#define BOOST_ END_ NAMESPACE (SEQ)    \
        BOOST_PP_SEQ_FOR_EACH(_PP_NS_END_FUNC, ~, SEQ)

#endif     //BOOST_NAMESPACE_UTILITY_HPP_

Then the code can be more clear and easy-reading:

BOOST_BEGIN_NAMESPACE((boost)(asio)(ip))
//namespace boost{namespace asio{namespace ip{

...        //to something

BOOST_END_NAMESPACE((boost)(asio)(ip))    //}}}

c++11 inline namespace also can work:

inline BOOST_BEGIN_NAMESPACE((detail))
...        //to something
BOOST_END_NAMESPACE((detail))

I wander to know whether this util could be a part of boost.

Thanks a lot.
