 * This file is critical for vm2. It implements the bridge between the host and the sandbox.
 * If you do not know exactly what you are doing, you should NOT edit this file.
 *
 * The file is loaded in the host and sandbox to handle objects in both directions.
 * This is done to ensure that RangeErrors are from the correct context.
 * The boundary between the sandbox and host might throw RangeErrors from both contexts.
 * Therefore, thisFromOther and friends can handle objects from both domains.
 *
 * Method parameters have comments to tell from which context they came.
