//#region src/fp/array/at.d.ts
/**
 * Creates a function that retrieves elements from the piped array at the specified indices.
 *
 * Negative indices count back from the end of the array, matching the main {@link at}
 * implementation. Use the returned function with {@link pipe}.
 *
 * @template T - The type of elements in the array.
 * @param indices - The indices of the elements to retrieve from the piped array.
 * @returns A function that maps a readonly array to a new array of selected values.
 *
 * @example
 * import { at, pipe } from 'es-toolkit/fp';
 *
 * pipe([10, 20, 30, 40], at([1, -1]));
 * // => [20, 40]
