It does not beat ruby's elegance. ;-)
In ruby, Arrays have operator[], where with one parameter it returns an
Object (the object at the given index), but if operator [] has two
parameters, then it returns an array with the given range.
[1,2,3,4,5,6][1]
=> 2
[1,2,3,4,5,6][1,3]
=> [2, 3, 4]
Of course you can do
a = [1,2,3,4,5,6]
a[1] or a[1,3]
I just wanted to enhance that the method [] is available on a explicit
array as much as you can see Integer methods doing 3.methods or get the
abs by doing -10.abs
