int[*] is a one-dimensional array of indeterminant length.
int[] is an array of indeterminant dimensions, each of indeterminant 
length:

	> int[] a = (int[1,2]) { };

works, while

	> int[*] b = (int[1,2]) { };
	->     int[*] b = (int[1, 2]) {};
	<stdin>:8: Incompatible types, storage 'int[*]', value 'int[1, 2]', for initializer

Yeah, but that requires additional work....
