I have the following type definition:

enum MixedResultType {
  Abstract = 'ABSTRACT',
  Section = 'SECTION',
}

type MixedSearchResult =
  | {
      type: MixedResultType.Abstract;
      data: Abstract[];
    }
  | {
      type: MixedResultType.Section;
      data: Section[];
    };

Abstract and Section share no common properties.

If I define an object with MixedSearchResult:

const result: MixedSearchResult = {
 type: MixedResultType.Abstract,
 data: abs as Abstract[],
};

I will get an error saying

Type 'Abstract[]' is not assignable to type 'Abstract[] | Section[]'

The end goal is to have a MixedSearchResult array with different type of search results.
