To prevent a misunderstanding, immutable can be initialized at run time 
as well. On the other hand, immutable initialized at compile time was 
surprising to me when I learned it recently:

import std;

immutable string p;

shared static this() {
  p = environment["PATH"];  // <-- Run time
}

// Ali learned this relatively recently
// (immutable at compile time):
immutable lines = import("myfile.txt").splitter('\n').array;
pragma(msg, lines);

void main() {
}
