 When a type has been declared this is attached to a list or string.  When
 later some expression attempts to change the type an error will be given: >
 	var ll: list<number> = [1, 2, 3]
-	ll->extend('x')  # Error, 'x' is not a number
+	ll->extend(['x'])  # Error, 'x' is not a number
 
 If the type is inferred then the type is allowed to change: >

+	[1, 2, 3]->extend(['x'])  # result: [1, 2, 3, 'x']
