I wish below would "just work"


// ----
module test;

import std;

@safe
void main()
{
     //int[5] arr = [1, 2, 3, 4, 5]; // nope. won't work with 
.parallel
     int[] arr = [1, 2, 3, 4, 5];// has to by dynamic to work with 
.parallel ??

     int x = 0;

     foreach(n; arr.parallel) // Nope - .parallel is a @system 
function and cannot be called in @safe
     {
         x += n;
     }

     writeln(x);
}
