Hi,

In this simple code, I expect that the size of the fusion::set is
equal to one, because keys are the same.
Why the size is equal to two?

#include <boost/fusion/container/set.hpp>
#include <boost/fusion/include/set.hpp>
#include <boost/fusion/container/set/set_fwd.hpp>
#include <boost/fusion/include/set_fwd.hpp>
#include <boost/fusion/sequence/intrinsic/size.hpp>
#include <boost/fusion/include/size.hpp>
#include <iostream>

int main() {
   typedef boost::fusion::set<int, int> set1;
   set1 s1;

   std::cout
   << "size1 = " << boost::fusion::result_of::size<set1>::type::value
   << ", size2 = " << boost::fusion::size(s1)
   << std::endl;
}

Thanks!
