Comment(by anonymous):

 Here is one problem. Lets look at the following declaration:

 {{{
 options_description_easy_init::operator()(const char* name,
                                           const value_semantic* s,
                                           const char* description);
 }}}

 Note that you can't replace it with

 {{{
 options_description_easy_init::operator()(const std::string& name,
                                           const value_semantic* s,
                                           const std::string& description);
 }}}

 because the latter is not exception-safe due to unspecified order of
 arguments' evaluation.
