Support TypeScript 4.9 class auto-accessors ("accessor" keyword)

[eddyw]

What is the problem this feature would solve?

The decorators proposal is stage 3 and one of the things it introduces (besides .. decorators) is class auto-accessors.

class Foo {
	accessor username: string = "";
	accessor password: string = "";
}

Currently outputs:

$ bun stuff.ts

error: Expected ";" but found "username"

        accessor username: string = "";
          ^
[...]/stuff.ts:18:11 334

$ bun --revision
1.0.3+25e69c71e70ac8a0a88f9cf15b4057bd7b2a633a
$ uname -mprs
Darwin 23.0.0 x86_64 i386

What is the feature you are proposing to solve the problem?

It's been implemented in TypeScript 4.9 as well as supported in EsBuild v0.18.5. It'd be great to have support for this in Bun.

1. esbuild v0.18.5 - release notes
2. TypeScript 4.9 - Auto-Accessors in Classes
3. Proposal Decorators - Class Auto-Accessors

Opening this issue to track when it eventually land in Bun.

What alternatives have you considered?
