 +======Synopsis:​======
 +$__getitem__(<​array>​ <​item#>​) \\ 
 +$__igetitem__(<​array>​ <​index#>​)
 +
 +======Technical:​======
 +These functions are used to fetch data held in the given array.
 +
 +The $__getitem__() function retrieves data based on its item number in
 +the array (counting from zero, the order in which the data was entered).
 +
 +The $__igetitem__() function retrieves it based on its index number
 +(counting from zero, in a sorted order).
 +
 +These functions only affect arrays created with $[[setitem]]().
 +
 +======Practical:​======
 +These functions are used to get an item in an array. ​ The applications
 +for these function should be obvious. ​ The $__igetitem__() function, in
 +particular, is useful for showing an array'​s contents in alphabetical
 +order.
 +
 +======Returns:​======
 +array item data, or empty string if array or item is not found
