 I use boost 1.34.0, python 2.5.1
 User can modify the enum value, But enum should be a const value(read
 only).

 {{{
 #!cpp
 enum my_enum{my_value};
 struct my_s{ enum{ my_value2 };};

 void my_export
 {
     enum_< my_enum >("my_enum") .value("my_value", my_value);
     scope* my_s_scope = new scope(class_< my_s>("my_s", init<  >()));
     scope().attr("my_value2") = (int)my_value2;
     delete my_s_scope;
 }
 }}}

 {{{
 #!python
 #in python
 module.my_enum.my_value = 1
 print module.my_enum.my_value
 module.my_s.my_value2 = 2
 print module.my_s.my_value2
 # we can modify the const value.
 # output
 #  1
 #  2
 }}}
