As for C(++), not standardized in the language itself. With LDC:

These are for when you are working on the compiler's source
itself.

Hello,
I've recently decided to pick up D, and have started doing some
exercises on
https://exercism.io/ (a non-profit programming exercise
platform), which I think is an excellent way to pick up the
basics in a new language.
While doing the exercises on my own is rewarding already, I would
import std.stdio;
ubyte[] extend(in uint[] arr)
{
ubyte[] result;
foreach (n; arr)
{
if (n < 10)
{
result ~= n;
// source/app.d(10,11): Error: cannot
append type const(uint) to type ubyte[]
