Reports non-idiomatic is type checks for an object.

It's recommended to replace such checks with reference comparison.

Example:

  object Foo

  fun foo(arg: Any) = when {
      arg is Foo -> ...
      arg !is Foo -> ...
  }

After the quick-fix is applied:

  object Foo

  fun foo(arg: Any) = when {
      arg === Foo -> ...
      arg !== Foo -> ...
  }
