Note that (with dmd 2.049)

pure int f(int i)
{
  return ++i;
}

doesn't compile, yet

pure auto f(int i)
{
  return ++i;
}

does work (int return type is replaced with auto).

Also http://www.digitalmars.com/d/2.0/function.html section "Pure Functions"
gives an example of assignment to parameter,

  i = y;    // ok, reading immutable global state
