immutable string a;
struct Test {
   static immutable string b;

shared static this() {
   a = "foo";
   Test.b = "bar";

Error: cannot modify immutable expression b

Hmm... should work, I think...
But this works in any case:

immutable string a;
struct Test {
   static immutable string b;
   shared static this() {
     b = "bar";
   }
}

shared static this() {
   a = "foo";
}

void main(){
     assert(a == "foo");
     assert(Test.b == "bar");
}

Ah, did not know that. Thank you!
