How can it be an implementation detail if the compiler accepts 
code like this? You can't do anything like this with a dynamic 
foreach, it must to be unrolled at compile-time:


import std.typetuple, std.string;
void main() {
     foreach (x; TypeTuple!(0, 1, 2)) {
         mixin(format("int x%d;", x));
     }
}
