Re: Indenting vs begin/end

Take a look at the Clean 1.0 system report somewhere at
http://www.cs.kun.nl/~clean/


In this language you can optionally leave out begin/ends, brackets,
etc. but then you have obey certain "off-side" rules (like in the
language Miranda).


This means that the function definition




primes = sieve (gen 2); where {
    sieve [p:x] = [p:sieve (filter p x)]; gen n = [n:gen (n+1)];
    filter p [a:x] | a mod p == 0 = filter p x; | otherwise = [a:filter p x];
}




is equal to




primes = sieve (gen 2)
where
      sieve [p:x] = [p:sieve(filter p x)]
      gen n = [n:gen (n+1)]
      filter p [a:x]
              | a mod p == 0 = filter p x
              | otherwise = [a:filter p x]




Neat, huh?
