Description

We treat arrays as Lists in may respects. There are methods from List that have been grafted unto arrays however there is no contains() method which would come in handy in scenarios like the following one

if(!arrayOfObjects.contains(element)) {
    arrayOfObjects << elements
}

One way to do it currently is this

if( !(element in arrayOfObjects) ) {
    arrayOfObjects << elements
}

Notice the additional () around the expression
