The famous case in support of Go syntax:

In D syntax, a nested array
	int[A][B] x;
has to be indexed as
	x[b][a]
(implying that b runs over 0..B and a over 0..A)

After all, it is an "array of B arrays of A integers", in other words an 
"integer-A-element-array-B-element-array".

The same in Go ordering is more straightforward:
	[B][A]int x
