ERROR TS2322: Type '~lib/object/Object' is not assignable to type 'module/A'.

class Nested {}

class A {
  b: Nested = new Nested();
  // `this` causes some kind of assignable error?
  c: Nested[] = [this.b];
}

export function add(): i32 {
  let a = new A();
  return 42;
}

It produces the following error...

;; ERROR TS2322: Type '~lib/object/Object' is not assignable to type 'module/A'.
;;    :
;;  7 │ c: Nested[] = [this.b];
;;    │                ~~~~
;;    └─ in module.ts(7,18)

I found this error while working on my HTTP parser and needed to do a big refactor. I hit nearly 280 errors because I had to port my lexer combinator rules over to class properties.

Is there a workaround? And where might the problem be located in the compiler? I would love to help.

Additional information:

There were no constructors in any of these classes.

I suppose this one has been fixed in #2635?
