I want int[][] like this -> [[1, 2, 3, 4, 5], [6, 7, 8, 9, 10], [11, 12, 13, 14, 15]] Any help will be appreciated. note: to2Darray is not a valid statement ;-) // --- module test; import std; void main() { int[][] arrayOfarrays = iota(1, 16).chunks(5).to2Darray; // how to convert this into [][] } // ---
