Don't forget the

   (A >:< B)

operator:

   def fib(n):
       curr = prev = 1
       for _ in range(n):
           (curr >:< prev) += prev
       return curr

Obviously, we see immediately the need for the Pythonic improvement:

   def fib(n):
       curr = prev = 1
       for _ in range(n):
           curr >+=< prev
       return curr
