Note that for structs, there is no need to define a constructor if parameters map on fields one on one and the constructor does nothing else:

And if they don't map one on one, the caller can use a static or dynamic initializer instead:

    Rectangle r2 = {width:6, height:7, x:4, y:5};
    writeln(r2); // Rectangle(4, 5, 6, 7, Blue)

For classes, though, this isn't available.

Your proposal wouldn't work in a nested class, as this and super refer to the nesting class.

nobody should use constructor on structs

and nobody should use classes for basic stuffs that should be simple pod

It's not advice. It's explaining what the example code means with the new feature.

That's the first time I've ever heard that.

What if you want a vector reference type on the heap, e.g. for immutable vectors to share across threads? new Struct would return a pointer, so += won't work. Or if you want it to be synchronized?

It takes a lot of effort, so either you have to care enough about it to do it yourself or you need to find someone else who feels the same.

All you get by asking for a feature in the forum is a bunch people yapping about it.

Im only telling you this so you dont have unrealistic expectations regarding your request. And it is worth considering that it's probably something that's been suggested before, I dont remember for sure, but probably. And there's pretty much always bigger fish to fry.

Please add this and super to constructor parameters.

This is the result of poorly designed software, you always want to do more esoteric things; "the java way"

...

    Rectangle r2 = {width:6, height:7, x:4, y:5};
    writeln(r2); // Rectangle(4, 5, 6, 7, Blue)

That doesn't allow fields to be dynamically initialized automatically, like constructors do.

For simple code, you can use my boilerplate library https://code.dlang.org/packages/boilerplate

https://dlang.org/spec/struct.html#dynamic_struct_init
Is this not... "automatic"?
