Something along the way

     unittest
     {
         import std.typecons : Tuple, tuple;
	alias pair = Tuple!(string, int);

         pair[] values;
         values ~= tuple("du", 7);
         values ~= tuple("Vino", 3);
         values ~= tuple(",", 4);
         values ~= tuple("hur", 5);
         values ~= tuple("Hej", 2);
         values ~= tuple("?", 8);
         values ~= tuple("mår", 6);

         import std.algorithm : sort, each;
         import std.stdio : write;
         values.sort!((p1, p2) => p1[1] < p2[1])
               .each!(p => write(p[0] ~ " "));
     }
