Surely you know by now what I'm going to say... just write a 
normal function.

module typegame.solution;

string easy(T...)() {
         string result;

         // I separate out the display name from the seen name
         // since you might pass a.Foo and b.Foo and want it
         // differentiated in comparison but both displayed "Foo"
         string lastDisplay;
         string lastSeen;
         int repetitionCount;

         void finish() {
                 if(repetitionCount != 2 && repetitionCount != 3)
                         return;
                 if(result.length)
                         result ~= " ";
                 if(repetitionCount == 2)
                         result ~= "double ";
                 else
                         result ~= "triple ";

                 result ~= lastDisplay;
         }

         foreach(t; T) {
                 if(t.mangleof == lastSeen) {
                         repetitionCount++;
                 } else {
                         finish();
                         lastSeen = t.mangleof;
                         lastDisplay = t.stringof;
                         repetitionCount = 1;
                 }
         }

         finish();

         return result;
}
