IMO Nim is an advanced, complied superset of python

fibber.nim

import math, strformat, times

func fib(n: int): int =
    if n <= 2:
        return 1
    else:
        return fib(n - 1) + fib(n - 2)

when isMainModule:
    let x = 47
    let start = epochTime()
    let res = fib(x)
    let elapsed = epochtime() - start
    echo(&"Nim Computed fib({x})={res} in {elapsed} seconds")

fibber.py

import time

def fib(n: int) -> int:
    if n <= 2:
        return 1
    else:
        return fib(n - 1) + fib(n - 2)

if __name__ == "__main__":
    x = 47
    start = time.time()
    res = fib(x)
    elapsed = time.time() - start
    print(f"Py3 Computed fib({x})={res} in {elapsed} seconds")

Python ran in 504.55 seconds
Nim ran in 4.63 seconds, same speed as C, and faster than any other language he tested:

C          Computed fib(47)=2971215073 in 4.58 seconds
Java       Computed fib(47)=2971215073 in 7.74 seconds
Go         Computed fib(47)=2971215073 in 10.94 seconds
JavaScript Computed fib(47)=2971215073 in 21.384 seconds
PyPy       Computed fib(47)=2971215073 in 93.63 seconds
Ruby       Computed fib(47)=2971215073 in 191.57 seconds
Python3    Computed fib(47)=2971215073 in 504.55 seconds
Perl5      Computed fib(47)=2971215073 in 980.24 seconds
R          Computed fib(47)=2971215073 in 2734.70 seconds

I'd imagine rust is equivalent to the nim and c speed.
