Destructuring and Typing

index.ts

class MyClass {
  // if destructured renaming wasn't a thing, this is
  // what I'd naturally expect. But it's already
  // valid JS syntax for renaming, obviously.
  constructor({ coreService: CoreService }) {
    //...
  }

  // maybe-ish?
  constructor({ coreService as CoreService }) {
    //...
  }
}
