Usage of forwardRef in NestJS decorator is not captured by SWC

[RobertMenke]

Describe the bug

NestJS has a strategy for dealing with circular dependencies, which is the use of a function called forwardRef.

Input code

// a.ts
@Injectable()
export class A {
    constructor(
          @Inject(forwardRef(() => B))
          private readonly b: B
    ) {}
}

// b.ts
@Injectable()
export class B {
    constructor(
          private readonly a: A
    ) {}
}

Config

{
  "jsc": {
    "parser": {
      "syntax": "typescript",
      "decorators": true
    },
    "transform": {
      "legacyDecorator": true,
      "decoratorMetadata": true
    },
    "target": "es2020",
    "keepClassNames": true,
    "baseUrl": "."
  },
  "module": {
    "type": "commonjs",
    "strictMode": true
  }
}

Expected behavior

I would expect that the code compiles because tsc does not error

Actual behavior

ReferenceError: Cannot access 'MyClassName' before initialization

Version
