I find this a bit strange:
irb(main):001:0> a=[1,2,3]
=> [1, 2, 3]
irb(main):002:0> a[2,1]
=> [3]
irb(main):003:0> a[3,1]
=> []
irb(main):004:0> a[4,1]
=> nil
Both a[3,1] and a[4,1] use out of range indices, so why is there a difference?
(Sorry if this has come up before, I searched but could not find)
