💻 Code

A demo repo

// In a project with references that I forced to export a "private export". I export it as a string value which breaks .d.ts creation
interface ReferenceTo<T extends string> {
  (value: T): T;
  value: T;
}


// The `as "…"` part
export { ReferenceTo as "~ ReferenceTo" };

🙁 Actual behavior

I get the error

a/out/lib/y.d.ts:1:39 - error TS1110: Type expected.

1 export declare const x: import("./x").~ ReferenceTo<"x">;
~

a/out/lib/y.d.ts:1:39 - error TS1110: Type expected.

~

🙂 Expected behavior

It will export it as a computed value so it work

export declare const x: import("./x")["~ ReferenceTo"]<"x">;
