So due to the way we try to sandbox modules from each other, instance of doesn't work across module boundaries. The 3 files attached show this problem. The interesting part is

exports.test_InstanceOf = function () {
  var a1 = require('a1');
  var a2 = require('a2');
  asserts.instanceOf(a1.array(), Array, "Array in a1 is instanceof main Array");
  asserts.instanceOf(a2.array(), Array, "Array in a2 is instanceof main Array");
  asserts.instanceOf([1,2,3], Array, "sanity check");
}

The .array() functions are defined in the moudles and return [1,2,3]. Only the sanity check test of the 3 above passes.
