[List] new

Creates a new array. An array is a collection of items. To create a new array, send the 'new' message to the array. To add an element send the 'push:' message to an array with the element to add as an argument. Instead of using the push-message you can also use the • message. This message is suitable for vertically written arrays because they look similar to lists seen in regular documents. Besides 'push:' and • you can also use the ; message to push an new element on top of the array. The arrow message is the same as 'new' plus 'push:', just a shorter notation. The ; message is very suitable for horizontally written arrays. Finally, the last example depicts a notation using just ascii characters.

 ☞ meals :=
	List new
	• 'hamburger'
	• 'pizza'
	• 'haggis'.

 ☞ todo := List ← 'dishes' ; 'cleaning'.
