I have timed it, to see the relative performance of some DMD versions (LDC is
twice faster on this program).

Timings, no input, dmd compiler, best of two, seconds:
  v1.061:      61
  v1.061:      62 (struct spheres) [Sphere(1e5, Vec3(1e5+1,...

  v2.046:      73

  v2.047beta:  74
  v2.047beta:  75 (__gshared spheres)
  v2.047beta: 232 (enum __gshared spheres)
  v2.047beta: 210 (enum spheres)  
  v2.047beta:  68 (struct spheres) [Sphere(1e5, Vec3(1e5+1,...

The timings are a bit strange.
