    Summary: `through` and `through_and` causes a double free if the map function panics

    Details: `through` and `through_and` take a mutable reference as well as a mapping function to change the provided reference. They do this by calling `ptr::read` on the reference which duplicates ownership and then calling the mapping function. If the mapping function panics, both the original object and the one duplicated by `ptr::read` get dropped, causing a double free.
