 *
 * @remarks
 * The returned function bails if any intermediate path values are non-indexable
 * (only the very last path element can be missing in the actual object
 * structure). If successful, returns original (mutated) object, else
 * `undefined`. This function provides optimized versions for path lengths <= 4.
