No need to. Since you said it didn't match your experience I 
checked. It turns out I was using last years ldc (0.15.2-beta2). 
Version 0.16.0 behaves similar.
But for version 0.17.1 I get the following plots. ldc looks much 
better. I make a note to check the fast math version once that's 
release. But the code is integer heavy.
