function id<T>(x: T): T { return x; } function stringId(x: string): string { return x; } function numberId(x: number): number { return x; } // OK: ((x: string) => string) | ((x: number) => number) const f = true ? numberId : stringId; // Actual: <T>(x: T) => T // Expected: (x: string) => string const g = true ? id : stringId;
