Thanks for the long explanation but when I am referring to the meta
universal syntax, I am referring to a feature I will be adding to the
Fornux C++ Superset source-to-source compiler (if you wanna go into
details). That feature will convert:

#include <list>
#include <iostream>

using namespace std;


struct A
{
     virtual void foo(list<int> & l)
     {
         cout << __PRETTY_FUNCTION__ << endl;
     }
};

int main()
{
     list<int> l = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9};

     A a;

     a.foo(l);
     a.foo(list<int>{0, 1, 2, 3, 4, 5, 6, 7, 8, 9});
}


Into:

#include <list>
#include <iostream>

using namespace std;


struct A
{
     virtual void foo(list<int> && l)
     {
         cout << __PRETTY_FUNCTION__ << endl;
     }
};

int main()
{
     list<int> l = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9};

     A a;

     a.foo(move(l));
     a.foo(move(list<int>{0, 1, 2, 3, 4, 5, 6, 7, 8, 9}));
}


Therefore mimicking non-const references to r-values. One complexity
step taken away!


Thanks,
