Henrik Lindberg created an issue   Puppet / PUP-6046 improve getting nested keys from hash Issue Type: Bug Assignee: Unassigned Created: 2016/03/11 8:25 AM Priority: Normal Reporter: Henrik Lindberg In a blog post, R.I.Pienaar writes: This [structured facts] makes everything better. It’s also structured data but this is still a bit awkward in Puppet: $x = $facts["foo"]["bar"]["baz"] There seems to be no elegant way to handle a missing ‘foo’ or ‘bar’ key, things just fail badly in ways you can’t catch or recover from. On the CLI you can do facter foo.bar.baz so we’re already careful to not have “.” in a key. We can actually use multiple keys in an access operator (you can directly slice an array with two arguments (from, to). We could use this for hash as well to mean a progression of key lookups producing undef if one key produces undef.
