Interesting. How much of the JS infrastructure do you need for this stuff to work?

I'm in the middle of creating a JS port for embedded systems (yes, I know about Espruino. It made some fundamental decisions about object implementation that I find unacceptable) and it would be nice to be able to lean into something like this to avoid implementing huge chunks of the more advanced language bits.

Side note: I'm the person who did the first Nintendo DS port of Gambit so its interesting to see how all this comes full circle.
