+For array literals, if the length is present the constructed array has that many
 elements; trailing elements are given the approprate zero value for that type.
-If it is absent, the size of the array is the number of elements. It is an error

+If it is absent, the length of the array is the number of elements. It is an error

+In either case, the length is known at compile type and thus the type of an
+array literal is always a fixed array type.
