Destructuring with rename incorrectly inferred as any

[remcohaszing]

TypeScript Version: Nightly or 3.9.x

Search Terms: never destructure

Expected behavior: The type of shouldBeNever is never.

Actual behavior: The type of shouldBeNever is any.

The issue also exists for synchronous functions, but the asynchronous example shows that everything works as expected when using Promise.then().

The same issue exists for unknown as well.

Code

interface AxiosResponse<T = never> { 
    data: T;
}

declare function get<T = never, R = AxiosResponse<T>>(): Promise<R>;

async function main() {
    // These work examples as expected
    get().then((response) => { 
        // body is never
        const body = response.data;
    })
    get().then(({ data }) => { 
        // data is never
    })
    const response = await get()
    // body is never
    const body = response.data;
    // data is never
    const { data } = await get<never>();

    // The following does not work as expected.
    // shouldBeNever should be never, but is any
    const { data: shouldBeNever } = await get();
}

Output

"use strict";
async function main() {
    // These work examples as expected
    get().then((response) => {
        // body is never
        const body = response.data;
    });
    get().then(({ data }) => {
        // data is never
    });
    const response = await get();
    // body is never
    const body = response.data;
    // data is never
    const { data } = await get();
    // The following does not work as expected.
    // shouldBeNever should be never, but is any
    const { data: shouldBeNever } = await get();
}
