# Description
This change ensures that the ordering of map keys when reading YAML
files is consistent. Previously a `HashMap` was used to store the
mappings, but that would result in non-deterministic ordering of the
keys. Switching to an `IndexMap` fixes this.
Fixes https://github.com/nushell/nushell/issues/8662
