Does DMD unroll loops?

[Jascha Wetzel]

is there a way to make DMD unroll loops?
i can use mixins instead, but it's ugly...

struct Vec(T,int dim)
{
  alias Vec!(T,dim) vec_t;

  T[dim] data;

  void opAddAssign(vec_t v)
  {
    foreach ( int i, inout d; data )
      d += v.data[i];
    // alternatively:
    // for ( int i = 0; i < dim; ++i )
    //  data[i] += v.data[i];
  }
}
