I failed to get numba installed on a Raspberry Pi 2, and I'd been wanting to try Nim, which turned out to be easy to compile on the RPi running Ubuntu.

  nim -r -d:release c rw_fibn.nim                                                  
  ...

  Hint: operation successful (12152 lines compiled; 2.632 sec total; 8.870MB; Release Build) [SuccessX]
  /home/rw/git/Nim/examples/rw_fibn

  Result = 8944394323791464
  elapsed time: 5.376946926116943

My first try at translating Python to Nim:

$ cat rw_fibn.nim

  import times

  proc fibn(reps: int64, num: int): int64 =
    var z: int64
    for r in 1..reps:
      var
        p1, p2: int64 = 1
        rnum: int = num - 2
      for i in 1..rnum:
        z = p1 + p2
        p2 = p1
        p1 = z

    return z

  var start: float = times.epochTime()
  var res = fibn(10_000_000, 78)
  var finish: float = times.epochTime()

  echo("Result = ", res)
  echo("elapsed time: ", finish - start)
