you can always create a mixin

replacing 1 line of code with 30 isnt great

how often do you need this 'feature'? can you show a real world usecase?

I've been programming in D for many years because of such wonderful language features. But, in my opinion, we need to focus on stabilizing and fixing what we already have. Speaking of static arrays, I’d like to remind that we've had a long-standing bug with a segmentation fault: type inference doesn't work for a static array of type real[1].

void main() {
    import std.stdio : writeln;
    real[1] arr = 0;
    writeln(arr); // SEGFAULT
}

Correction: array output to screen does not work.
