As far as I recall, foreach_reverse is deprecated in favour of 
range operations.
ie.
  import std.algorithm, std.range;

  static if(forward)

      items.each!(item => doStuff());
  }
  else
  {
      items.retro.each!(item => doStuff());
  }

As for your question, I suggest writing a range function that 
calls retro conditionally. Something like,

  items.direction!(forward).each!(item => doStuff());

Won't this pattern fail if items is a type implementing opApply 
and/or opApplyReverse?
