Part of #43927. Currently, arrays can only be nested three layers deep. While it's not likely we'll ever even need that many layers, there's no good reason for this limit; it only exists because there are only three array indices to use (i, j and k) ~> figure out a simple, general way to generate an unlimited number of indices and remove the restriction.
