Thanks Kenji, I will use xformat. BTW, why is it named &quot;x&quot;format? Would not &quot;s&quot;format be a better name? Where &quot;s&quot; could stand for string.<div><br></div><div>Also I feel, std.string.format should work for BitArray and BigInt too. Both these types are defined as part of phobos.</div>
