Multiple ArrayLike imports being added

[machty]

I'm using rehearsal fix in a piecemeal manner on some components and sometimes it causes large number of ArrayLike imports to be added to the top of the file (even though the ArrayLike import is not even referenced in the final code).

Input file:

import type ChartControls from "@futureproofretail/analytics/services/chart-controls";
import Component from "@ember/component";
import { readOnly } from "@ember/object/computed";
import { inject as service } from "@ember/service";

import classic from "ember-classic-decorator";

@classic
export default class AddMetric extends Component {
  @service
  declare chartControls: ChartControls;

  // @ts-expect-error @rehearsal TODO TS7008: Member 'metrics' implicitly has an 'any' type.
  @readOnly("chartControls.metrics") metrics;
}

Output:

import type ChartControls from "@futureproofretail/analytics/services/chart-controls";
import Component from "@ember/component";
import { readOnly } from "@ember/object/computed";
import { inject as service } from "@ember/service";

import classic from "ember-classic-decorator";
// @ts-expect-error @rehearsal TODO TS6133: The declaration 'ArrayLike' is never read or used. Remove the declaration or use it.
import { ArrayLike } from "node_modules/@glint/environment-ember-loose/-private/intrinsics/each";
// @ts-expect-error @rehearsal TODO TS2300: Duplicate identifier 'ArrayLike'.
import { ArrayLike } from "node_modules/@glint/environment-ember-loose/-private/intrinsics/each";
// @ts-expect-error @rehearsal TODO TS2300: Duplicate identifier 'ArrayLike'.
import { ArrayLike } from "node_modules/@glint/environment-ember-loose/-private/intrinsics/each";
// @ts-expect-error @rehearsal TODO TS2300: Duplicate identifier 'ArrayLike'.
import { ArrayLike } from "node_modules/@glint/environment-ember-loose/-private/intrinsics/each";
// @ts-expect-error @rehearsal TODO TS2300: Duplicate identifier 'ArrayLike'.
import { ArrayLike } from "node_modules/@glint/environment-ember-loose/-private/intrinsics/each";
// @ts-expect-error @rehearsal TODO TS2300: Duplicate identifier 'ArrayLike'.
import { ArrayLike } from "node_modules/@glint/environment-ember-loose/-private/intrinsics/each";
// @ts-expect-error @rehearsal TODO TS2300: Duplicate identifier 'ArrayLike'.
import { ArrayLike } from "node_modules/@glint/environment-ember-loose/-private/intrinsics/each";
// @ts-expect-error @rehearsal TODO TS2300: Duplicate identifier 'ArrayLike'.
import { ArrayLike } from "node_modules/@glint/environment-ember-loose/-private/intrinsics/each";
// @ts-expect-error @rehearsal TODO TS2300: Duplicate identifier 'ArrayLike'.
import { ArrayLike } from "node_modules/@glint/environment-ember-loose/-private/intrinsics/each";
// @ts-expect-error @rehearsal TODO TS2300: Duplicate identifier 'ArrayLike'.
import { ArrayLike } from "node_modules/@glint/environment-ember-loose/-private/intrinsics/each";

@classic
export default class AddMetric extends Component {
  @service
  declare chartControls: ChartControls;

  // @ts-expect-error @rehearsal TODO TS7008: Member 'metrics' implicitly has an 'any' type.
  @readOnly("chartControls.metrics") metrics;
}

I found that if I comment out the @readOnly() (FYI I'm also trying to get rid of all the readOnly's in our app), the ArrayLike's don't get created.

It's not a big deal, it doesn't happen on every file, but it typically means when running rehearsal fix that I have to manually remove all these imports.
