Reply: OvermindDL1: "Re: [Boost-users] [spirit][qi] Iteration / string iterator"

can anybody explain to me why this example from the Spirit.Qi manual
works

http://www.boost.org/doc/libs/1_44_0/libs/spirit/example/qi/complex_number.cpp

and when I try to use the string iterators directly I get a horrific
compiler error? Something to do with string iterators being pointers
or something?

        std::string s = "(2, 3)"; // < line added to example
        bool r = phrase_parse(s.begin(), s.end(), //< only line
changed in the example was (first, last)
            // Begin grammar
            (
                    '(' >> double_[ref(rN) = _1]
>> -(',' >> double_[ref(iN) = _1]) >> ')'
                | double_[ref(rN) = _1]
            ),
            // End grammar

space);

Thank you
Alfredo
