The with(proxy) pattern is super clever. It looks like that was created by someone else. Kudos to whoever came up with it. It’s a really nice hack.

Thanks. The "with(proxy)" part specifically would be mine. The old Google Caja, from the EcmaScript-5 days preceding Proxies, did something similar: https://github.com/google/caja/blob/master/src/com/google/ca...
The full new pattern, combining "with(proxy)" with a clever use of direct "eval", is from Caridy Patino of Salesforce.
The modern Realms Shim https://github.com/Agoric/realms-shim , and the SES Shim which builds on it https://github.com/Agoric/SES , is a collaboration of Agoric and Salesforce, especially JF Paradis of Salesforce.
We have come to refer to the fragment of code with the "with(proxy)" and the direct "eval" as the "Eight magic lines of code" and "The heart of the shim". It is explained at https://www.youtube.com/watch?v=9Snbss_tawI&list=PLKr-mvz8uv... and https://www.youtube.com/watch?v=mSNxsn0pK74&list=PLKr-mvz8uv...
