+		Generic array, contains several elements of any type, accessible by a numerical index starting at 0. Negative indices can be used to count from the back, like in Python (-1 is the last element, -2 the second to last, etc.). Example:
+		[codeblock]
+		var array = ["One", 2, 3, "Four"]
+		print(array[0])   # One
+		print(array[2])   # 3
+		print(array[-1])  # Four
+		array[2] = "Three"
+		print(array[-2])  # Three
+		[/codeblock]
+		Arrays are always passed by reference.
