/**
 * Creates a memoized version of a function that caches only the last result.
 * The cache is invalidated when any of the arguments change.
 *
 * This is useful for expensive operations that are likely to be called
 * multiple times with the same arguments, like database queries or API calls.
 *
 * @param fn - The function to memoize
 * @returns A memoized version of the function
 *
 * @example
 * ```ts
 * const expensiveQuery = async (userId: string, limit: number) => {
 *   return await database.query(`SELECT * FROM users WHERE id = ? LIMIT ?`, [userId, limit]);
 * };
 *
 * const memoizedQuery = memoizeOnce(expensiveQuery);
 *
 * // First call executes the function
 * const result1 = await memoizedQuery("123", 10);
 *
 * // Second call with same arguments returns cached result
 * const result2 = await memoizedQuery("123", 10); // Uses cache
 *
 * // Call with different arguments invalidates cache and executes function
 * const result3 = await memoizedQuery("456", 10); // Executes function
 * ```
