Implements #4112 for #4159

Unfortunately It doesn't allow diferente types in the same vec, e.g. vec![..0, 4..7, 9..]

Thanks, looks good for me 👍

We might be able to somewhat workaround that by allowing Box<dyn RangeBounds<T>> and/or &dyn RangeBounds<T> as types there as well. That should allow at least to write vec![Box::new(..0), Box::new(4..7), Box::new(9..)] to represent these different types.
