: Works fine for me under 1.0.3. nice prime number generator..
: Was it susposed to crash or something?
Not at all...
It's just fun playing with lambda...
Two more examples: (assuming mail being faster than news, you'll know the
first one already)

fib=lambda x,f=lambda x,f:(x<=1) or (f(x-1,f)+f(x-2,f)): f(x,f)
for i in range(10): print fib(i)

...next...

# Hopefully someone will translate the following paragraph...

# Spielen mit lambda, map, reduce und Co ist ja ganz nett, aber bei diesem
# Teil hier habe ich mir das Hirn schon arg verrenken muessen, damit es
# ueberhaupt laeuft...
# Zugegebenermassen ist es nahezu unmoeglich, bei solchen Exzessen den
# Ueberblick zu behalten und so habe ich sicherlich nicht die "eleganteste"
# Loesung gefunden...
