1180	[boost.python] def_readwrite need a default docstring	qiaozhiqiang@…	troy d. straszheim	"the default docstring defined by def_readwrite is null, 
can boost.python add the type name of my_s::a as the default docstring? like the function's ""C++ signature"" docstring.

{{{
#!cpp
struct my_s
{
	int a;
};

void export_module
{
      class_<my_s >  s_class(""my_s"", init<  >());
      s_class.def_readwrite(""a"", &my_s::a);// __doc__ is empty, can boost.python add the type name of my_s::a as the default docstring? like the function's ""C++ signature"" docstring.
}

// I do this like this:
// get type name of data member of class 
template<typename T, typename C>
char const* MemberTypeName(T C::*)
{
	char const* name = typeid(T).name();
	return name;
}

// boost::python def_readwrite no docstring
// read write property
#define DEF_READWRITE(n, p) \
	def_readwrite((n), (p), std::string(""read write property, type is "") + MemberTypeName(p)).c_str())



void export_module
{
      class_<my_s >  s_class(""my_s"", init<  >());
      s_class.DEF_READWRITE(""a"", &my_s::a);// replace all auto genarated def_readwrite to DEF_READWRITE.
