Fun with lambda and map

[Gerson Kurz]

primes = lambda o:map(lambda a:filter(None,(map(lambda i:map(lambda
x:a.__setitem__(x,0),range(2*i,o,i)),range(2,o)),a)[1])[1:],[range(o)])[0]

print primes(20)

fibonacci = lambda x:map(lambda o:(map(lambda c:map(lambda
l:o.__setslice__(l[0],l[1],l[2]),([o[2]+3,o[2]+4,[o[0]]],[0,3,[o[1],reduce(lambda
x,o:x+o,o[:2]),o[2]+1]])),range(x)),o)[1],[[1,1,0]+range(x)])[0][3:]

print fibonacci(20)

(Note: These probably need python 2.2 to work because of the lambda
scope thing)
