  I had last run this comparison with rust 1.15. I reran it with 1.22 and they have added a few of the fixes. Unfortunately, none of them mattered for the n-body solution I was using. What is more, it was more than 10% slower than 1.15. Not impressed. I keep saying I want to try out rust as a c++ replacement where I work as soon as it settles down. I think that may he a while. The problem is that the rapid changes in c++ are causing us problems too as far as tool accreditation for safety and security. So a language that changes even faster is a non starter. But the comparable performance and superior safety guarantees is quite attractive in our case.

    A lot of this kind of thing is due to upgrading LLVM, which I'd imagine should cause similar variance with clang, but maybe not!
