The question should be if programming in d (page 177 
https://ddili.org/ders/d.en/Programming_in_D.pdf) should be 
authoritive here

blocks:

```d
import std.stdio;

immutable char[3] s;

shared static this() {
	s[0]='b';
     s[1]='a';
     s[2]='r';
}

void main(){
	writeln("In main()");
	writeln("s: ", s);
}
```
