merged release results

[Michael Caisse-2]

I've been testing out the release branch merge that happened today.

So far everything looks good with my grammars. I don't have a situation
with alternatives with literals so I've been creating some test harnesses
to check out the behavior based on my understanding. That also looks good
thus far.

As an aside... I ran into this peculiar issue. If have this... all is good:

----------------------------------

typedef boost::variant< int, std::string >  some_result_type;

int main()
{
   using qi::int_ ;
   using qi::alnum ;

   std::string some_value( "123" );
   std::string::const_iterator value_iter     = some_value.begin();
   std::string::const_iterator value_iter_end = some_value.end();

   some_result_type some_result;

   qi::rule< std::string::const_iterator, std::string() > rule_2 = ( *alnum );
   qi::rule< std::string::const_iterator, some_result_type() > rule_1 = (int_ | rule_2 );

   bool parse_good = qi::parse( value_iter, value_iter_end,
                                rule_1,
                                some_result   );

   return 0;
}

-----------------------------------


But if I change it so that there is one rule like this.... it fails to compile:

   qi::rule< std::string::const_iterator, some_result_type() > rule_1 = (int_ | (*alnum) );


It looks like the conversion from *alnum to std::string cannot be done. Is this
a bug or is it expected?

Yeah, that's the bug Joel attempted to fix a while ago. We still need to
work on this.
