Referencing class in function decorator call

I’m trying to pass a parameter to a decorator that references it’s own class:

export class SomeClass {
  public async handleError(error: Error): Promise<void> {
    // ... treating errors
  }

  @treat(SomeClass.prototype.handleError) // <- error here
  public async doSomething(): Promise<void> {
    // ... doing something
  }
}

But I’m getting this error:

ReferenceError: Cannot access 'SomeClass' before initialization

Is there anyway to do that or will I have to send the name of the treating function and find it inside the decorator?
