* 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.
