Why not just do this:

import std.typetuple;

T foo(T)(ref T thing)
{
     thing++; return thing * 2;
}

unittest
{
     foreach(Type; TypeTuple!(int, long, uint))
     {
         {
             Type tmp = 5;
             assert(foo(tmp) == 12);
         }

         {
             Type tmp = 0;
             foo(tmp);
             assert(tmp == 1);
         }
     }
}
