I don't find the re_init name very intuitive. From the name I would
imagine these functions be taking a `Box<T>` and a `impl Init<T, E>`,
dropping the content and produces a `Box<T>` again.
Would it make more to rename the existing functions to have `new` in
their name to indiciate that they allocate, e.g. `pin_new`, and have
these functions that only does initialisation `init`/`pin_init`?
Best,
Gary
