This is just a minimal repro, the real use case is for types/npm-ramda to generate DT compatible tests so that we could put them on DT, but we got problems.

Is there any reason we can't pass the enclosingDeclaration parameter to typeToString in the expect rule?

Code

(index.d.ts)

export type Or<T, U> = T | U;

(something-tests.ts)

import * as something from 'something';

declare const result: something.Or<string, number>;

// $ExpectType string | number
result;

Expected

no errors

Actual

ERROR: 6:1   expect   Expected type to be:
  string | number
got:
  Or<string, number>
