If you're looking for efficiency of generated code, use gdc or ldc. While dmd is the reference compiler with the latest and greatest bleeding-edge features, it's not known to be the best at generating optimized code, even if you run it with -O. If code size / efficiency is important to you, I highly recommend using gdc or ldc instead. T -- Век живи - век учись. А дураком помрёшь.
