11188	can not use repeat(int)[] with std::ref and phoenix::ref	vveesskkoo@…	Joel de Guzman	"Debian libboost-dev 1.55[[BR]]
When trying to compile a rule containing:

{{{
qi::repeat(std::ref(_n))[some_action]
}}}

the compiler complains:
/usr/include/boost/spirit/home/qi/directive/repeat.hpp:88:40: error: use of deleted function ‘std::reference_wrapper<_Tp>::reference_wrapper(_Tp&&) [with _Tp = int]’[[BR]]
T start() const { return '''type(0);''' }

In this situation qi:repeat (repeat.hpp:88:40) tries to create an iterator from[[BR]]
std::reference_wrapper<>(rhs_value) which is not possible as a reference is needed!

As a temporary workaround I used the following help type:

{{{
template<typename T>
class ref_rhs: public std::reference_wrapper<T> {
    private:
        T   _rhval;
    public:
        using std::reference_wrapper<T>::reference_wrapper; // inherit constructors

        ref_rhs(T&& rhs):
            std::reference_wrapper<T>(_rhval),
            _rhval(rhs)
        {}
};
}}}



and the call: qi::repeat(ref_rhs<T>(_n))[] works as expected.

May be qi:repeat should iterate internally with integers rather than with iterators as the documentation says that in the call qi::repeat(_n) _n must be convertible to int anyway.
