fun.STRUCT in plasm-fun.js

/**
   * STRUCT

  fun.STRUCT = function (items) {
    var transformations = function (o) {return o;};
    var objects = [];

    temp = [];

    items.forEach(function (item) {
      if (!(item instanceof plasm.Model) && 
          !(item instanceof plasm.Struct)) {
        transformations = COMP2([transformations, item]);
      } else {
        temp.push(APPLY([transformations, item]).clone());
        objects.push(APPLY([transformations, item]));
      }
    });

    return new plasm.Struct(objects, p);
  };

What's the necessity of the temp array in this code? it is declared locally, not visible outside the function, it isn't returned and it isn't never used (except that it is filled with clones of the items)...
