This gives a good idea of what the new API looks like. I think it is much clearer personally
| /// | ||
| /// If the path is not found, `None` is returned. | ||

I really wanted to add these tests / examples which lead to the other API changes

I re-exported the paths at the same top level

Love the chaining -- looks very sleek

Should it also impl FromIterator so people can do:
VariantPath::from_iter(["foo".into(), 0.into()])or
["foo".into(), 0.into()].into_iter().collect::<VariantPath>()There was a problem hiding this comment.

variant_getcompute kernel #7919Rationale for this change
While reviewing #7919 from @Samyak2 I found I wanted to write some additional tests directly for
Variant::get_pathWhen I started doing that I found it was somewhat awkward to write examples, so I added some new conversion routines to make it easier.
