Here's how I'm testing this:

$ dmd | head -n 1
DMD64 D Compiler v2.065
$ cat less_than.d
bool less_than (T)(auto ref T a, auto ref T b)
{
          return a < b;
}
void main()
{
          int a = 1, b = 2;
          assert(less_than(a, b));
          assert(less_than(a, 2));
          assert(less_than(1, b));
          assert(less_than(1, 2));
}
$ dmd less_than.d && echo ok
ok

If this exact code errors for you, it ... uhh ... could be
platform specific? Are you on Windows?
