Repro Code

export default class {
  public accessor a: string = 'a'

  public accessor c: string = 'c'

  // Should raise an error since `b` is before `c` in the alphabetical order, but does not
  public accessor b: string = 'b'

  /* If you invert `b` and `e()`, the following error will be raised:
    'Member null should be declared before all public instance method definitions. 16:3 - 16:34'
    (what means that `b` is recognized as a non-instance method, so the rule applies well,
    but it also means that the rule thinks that `b` is named `null`)
  */
  public e(): void {
    return
  }

  // Raise an error since `d` is before `e` in the alphabetical order, so the rule applies well
  public d(): void {
    return
  }
}

ESLint Config

{
  "rules": {
    "@typescript-eslint/member-ordering": [
      "error",
      {
        "default": {
          "memberTypes": [
            "accessor",
            "method"
          ],
          "order": "natural"
        }
      }
    ]
  }
}

tsconfig

{
  "compilerOptions": {
    "declaration": true,
    "declarationMap": true,
    "lib": [
      "dom", "esnext"

Expected Result

I expected the 7th line should report the error:

Member b should be declared before member c. 7:3 - 7:34

Actual Result

There was no error on 7th line.

Additional Info

If you invert b and e(), the following error will be raised:

Member null should be declared before all method definitions. 16:3 - 16:34

what means that b is recognized as a non-method, so the rule applies well, but it also means that the rule thinks that b is named null.

If you invert accessor and method in the eslint config:

{
  "rules": {
    "@typescript-eslint/member-ordering": [
      "error",
      {
        "default": {
          "memberTypes": [
            "method",
            "accessor"
          ],
          "order": "natural"
        }
      }
    ]
  }
}

a, b and c are well recognized as accessors according to the new error messages:

Member e should be declared before all accessor definitions. 14:3 - 16:4
Member d should be declared before all accessor definitions. 19:3 - 21:4

My assumption is that each accessor is treated as if it were named null.
