Nice test.  I'm new to D as well and can't comment on needed 
refactoring.   To confirm your results I compiled the D example 
using:

```
gdc -O2 speed.d -o speed
```

and measured 129 ms for the D program and 63 ms for the python3 
equivalent.

I'll be keen to see how this plays out since I'm using D as a 
faster alternative to python.
