Typescript: TS 3.6 generates broken types references in .d.ts files
TypeScript Version: 3.6.3
Search Terms: reference
Code
import { memoize } from 'lodash';
export const fn = memoize((num: number) => num + 1);
Expected behavior:
The resulting .d.ts file should look like this:
export declare const fn: ((num: number) => number) & import("lodash").MemoizedFunction;
Actual behavior:
Instead, since TS 3.6, this is what is generated:
/// <reference types="lodash/common/common" />
/// <reference types="lodash/common/array" />
/// <reference types="lodash/common/collection" />
/// <reference types="lodash/common/date" />
/// <reference types="lodash/common/function" />
/// <reference types="lodash/common/lang" />
/// <reference types="lodash/common/math" />
/// <reference types="lodash/common/number" />
/// <reference types="lodash/common/object" />
/// <reference types="lodash/common/seq" />
/// <reference types="lodash/common/string" />
/// <reference types="lodash/common/util" />
export declare const fn: ((num: number) => number) & import("lodash").MemoizedFunction;
This breaks the types for consumers of this .d.ts file:

Errr, far as I can tell, that error in @types/lodash is legit. it attempts to merge multiple interfaces that have the same name, but differing type parameters. The issue is that we fail to report it. Here's a more minimal repro without declaration emit involved. If you compile this:
/// <reference types="lodash" />
/// <reference types="lodash/common/common" />
you get no errors. If you compile this:
/// <reference types="lodash/common/common" />
/// <reference types="lodash" />
you get _all the errors_ - the errors are seemingly dependent on the order the files are found in!

Here's a minimal repro:
this has no error:
namespace ns {
interface Function<T extends (...args: any) => any> {
throttle(): Function<T>;
}
interface Function<T> {
unary(): Function<() => ReturnType<T>>;
}
}
this does:
namespace ns {
interface Function<T> {
unary(): Function<() => ReturnType<T>>;
}
interface Function<T extends (...args: any) => any> {
throttle(): Function<T>;
}
}

What about the references included in the emitted .d.ts file? It doesn't seem like these should be there, and it was working fine with TS 3.5.

They not _strictly_ needed in this case, since lodash's root happens to import all of those files itself, however the MemoizedFunction interface used is partially defined by augmentations in each of those files - we don't _know_ that the root lodash import pulled in all of them (it might not!), so we include direct refs, just to be safe and ensure the whole type as we know it is included.

@weswigham Will the fix be included in an eventual 3.6.4 release?

That would be up to @DanielRosenwasser, otherwise it's 3.7 bound.
