Neon

Goal: eliminate the necessity for neon-cli to wrap cargo so Neon projects can directly use all cargo commands in the Rust source directory.

Ideas:

1. Specify link flags in manifest

• On macOS need to pass -C link-args=-Wl,-undefined,dynamic_lookup
• Want users to be able to just type cargo build

    name: String

console.log(array1);

20:54	dherman	1. I imagine an object can only be a global object for one realm, right?
20:54	shu	oh my word yes
20:54	dherman	lol
20:54	dherman	don't panic
20:54	dherman	I'm just collecting invariants
20:54	dherman	(this is for the Realm API)
20:54	dherman	2. if you had a pre-existing object,
20:54	dherman	that isn't a global object
20:55	dherman	would it be problematic to allow using that object as a global object for a new realm?
20:55	shu	yes, the thing that's actually branded GlobalObjects internally can't be just any plain object

Proposed CORS Policy for Modules

Module MIME types are strict

If a module script receives a non-JS MIME type, it doesn't execute.

Modules are anonymous

Module scripts default to the anonymous CORS attribute.
