Avoid casting the input pointer to `*const _`, allowing the output pointer to be `*mut` if the input is `*mut`. This allows a number of `*const` to `*mut` conversions to be removed at the cost of slightly worse ergonomics when the macro is used with a reference rather than a pointer; the only example of this was in the macro's own doctest.
