Many of the modifications putting in `Box::new` calls also include a pointer to Issue 22405, which tracks going back to `box <expr>` if possible in the future. (Still tried to use `Box<_>` where it sufficed; thus some tests still have `box_syntax` enabled, as they use a mix of `box` and `Box::new`.) Precursor for overloaded-`box` and placement-`in`; see Issue 22181.
