To concur with what kkowalczyk, there is little expressiveness advantages to be gained for this specific example -- math is math, and outside of compressing it down to a couple of library calls, what could possibly be done better?

"they ended up with a language with the expressiveness of C and the speed of python."

This is just pure troll. Apparently you have a Python variant of this renderer that matches the already impressive Go performance? Please reveal it.
