The paper about Babel is written esthetically and inspiring, but lacks
deeper insight:
a) a functional language should not make use of ancient constructs like
"while" and "for", use iterators instead
b) the example on The GCD might be incomplete, pls. have a look
Thanks for the input,
Jens

Actually for-do uses iterators. I don't see why the programmer should
be burdened with adhering to the iterator protocol, the language can
do that for you. I am just lazy, probably an ancient habit.

It is complete. But it just defines a function gcd, so when you run
it, you will need to provide an expression that uses this function. Try:
fun gcd (a, b) =
while b != 0 do
b = a % b,
a = b
end;
a;
gcd (120, 35)
