I always feel like I'm listening to Hal - sorry Karsten - "We are all, by any practical definitions of the words, foolproof and incapable of error."

Now the point is - what is the difference between

1) Foolproof

2) Incapable of error

If there is no difference, then Hal is being deliberately redundant - what is this, pride? Or an efficient swap file?
