[BUG] Typescript enum compilation lost reference on version 0.18.9

[noyobo]

import { MyEnum } from './enums';
enum MyEnum2 {
  'A.A' = 'a',
  'aa' = 'aa',
}
console.log(MyEnum['A.A'], MyEnum2['A.A']);
console.log(MyEnum.aa, MyEnum2['aa']);
console.log(MyEnum['aa'], MyEnum2.aa);

output:

// src/index.ts
console.log(MyEnum["A.A"], "a" /* A.A */);
console.log("aa" /* aa */, "aa" /* aa */);
console.log(MyEnum["aa"], "aa" /* aa */);

// error: MyEnum not defined

• repl 0.18.9
• repl 0.18.8

Conditions that trigger the bug:

1. Import from other files
2. Using string subscripts, like enum['key']
