Currently in the `linker/compiler.ts` file, the **same identifier** is used in **two declarations**:
```typescript
export type CompilerOptions = { … }
…
export const CompilerOptions = new OpaqueToken('compilerOptions');
```
This breaks the API doc generation. I’m surprised that this was not flagged by the tsc.
The duplicate declaration was introduced in https://github.com/angular/angular/commit/46b212706b9162c22fb1523032d7e37c9155015a.
