Subject: idiomatic?

which is more idiomatic? amazing how similar ruby and python are.

and what does the guy mean with "pure" here:
http://www.linuxjournal.com/article/4834
that it is purely OO and consequent? Would Python be impure in his
meaning of pure?

def fib(n, a=0, b=1)
    if n > 0
        then fib(n-1, a+b, a)
        else a
    end
end

def fibo(n)
    a, b = 0, 1
    while n > 0
        a, b, n = a+b, a, n-1
    end
    a
end




def fac(n, acc=1)
    if n > 0
        then fac(n-1, n*acc)
        else acc
    end
end

def fac2(n)
    acc = 1
    for x in 1...n+1
        acc *= x
    end
    return acc
end
