why won't slicing lists raise IndexError?

Your original statement sounded like, "The else clause can never be 
executed," which would have been in direct opposition to the point, that 
slicing outside the limits would produce an empty list, not an 
exception.  I'm not sure why you are certain that there's never a reason 
to execute code in that case.

Perhaps I have a simulation on a conceptually infinite line, but only 
store the actual points needed.  The "non action" would be to extend the 
line.
