Speed Benchmarking

[ishandutta2007]

It's great that you have benchmarked against other C/C++ libs https://github.com/fredrik-johansson/arb#speed
But I am contemplating using C++ or python for some project since of late python's native arbitrary-precision have gotten really fast.
It would be great if you can update the speed with python3.8+ as well and if possible haskell(including LLVM-backend) as well.
It would be good if you can get these benchmarkes form the same host on which you did for those C/C++ libs. I would try to do the same once I have arb set up on my machine.
