Swift Operator Overloading Adding << On Array

gistfile1.swift

/*
In Swift, you can overload operators. A common operator in Ruby for working with arrays is <<, 
which is syntatic sugar for array.push(). Since Array's in Swift don't take bitwise operations, this is
an example demonstrating adding that operator to an array that contains any type.

As an extra tidbit, I've added >> to prepend an array with an object
*/

@infix func << <T>(inout array: Array<T>, item: T) {
    array.append(item)
}

@infix func >> <T>(inout array: Array<T>, item: T) {
    array.insert(item, atIndex: 0)
}
