String and Symbol types are different when used as a Hash key. By default the Vagrant machine names are set in Symbol format, but users may write their `host_vars` entries with String keys. This is a very simple way to ensure smooth experience, without having to coerce the data types during the config validation (e.g. with a library like Hashie, which is currently not in the Vagrant dependencies) See also: - https://bugs.ruby-lang.org/issues/5964#note-17 - https://github.com/intridea/hashie#keyconversion
