.. so instead of

array = ["hello"]
array.last += " world"
puts array

one could write

irb(main):001:0> a = ['foo','bar']
["foo", "bar"]
irb(main):002:0> a[-1]+='boozig'
"barboozig"
irb(main):003:0> a
["foo", "barboozig"]

While I know why the first attempt doesn't work, it would be nice if it 
would work. Is Array#last= all that's needed?
