   void poke(T)(size_t addr, T val) @safe pure {
      T* ptr;
      ptr[addr/T.sizeof] = val;
   }

   int i = 42;

   void main() @safe {
      writeln(i);
      auto whatever = cast(size_t)&i;
      poke(whatever, 666);
      writeln(i);
      poke(0, 0);
   }
   
   void writeln(A...)(A a) @trusted { import std.stdio; writeln(a); }
