-----------------------------------+----------------------------------------
 I wanna save a generator so that I can call it anytime without writing
 duplicate codes. Here is my code:

 #include<boost/spirit/include/karma.hpp>
 #include<boost/spirit/include/karma_format_attr.hpp>
 #include<list>
 #include<iostream>

 //auto par = '{' << -(boost::spirit::karma::int_ % ',') << '}';//This
 would lead error!
 int main(){
         using namespace std;
         namespace karma = boost::spirit::karma;
         list<int> l{1, 2, 4};
         auto par = '{' << -(boost::spirit::karma::int_ % ',') <<
 '}';//This would not!
         cout<<karma::format(par, l)<<endl;
         return 0;
 }

 When I define par out of a functint would leads to runtime error. Does I
 used it generator in a wrong way or it is a bug?
 GCC version 4.6.3
