Summary: Remove the now useless `handler` and adds the `traversal_func` and `processor` entries for `std::list`. This type is a bit weird as most of our sequential containers don't have any overhead on storing the element. I went for the same approach we take for maps where we have a shared `[]` element covering the map overhead and below that a `key` & `value`. As we only have a single element under it which doesn't have a logical name I went for `*`. Closes #315. Test Plan: - CI - Copied the relevant `std::vector` tests and updated the existing one.
