Henrik Lindberg commented on an issue   Re: can't make list of keys from hash using lambda stuff Hi, it works exactly as expected. Here are a few details that may have tripped you up: each produces what it received as input, what you do in the body of the lambda has no impact on the result reduce on a hash delivers each entry as an Array of [key, value] A small note; you are testing that: has_key($hsh, 'track') or $hsh['track'] != 'no' is redundant, you can simply do $hsh['track'] != 'no' since undef is not 'no', and if there is no value for the key undef is produced. Add Comment   Puppet / PUP-3562 can't make list of keys from hash using lambda stuff As per attached worked (tiny) example (NB: future parser): I am trying to do simple "data transformation" -- select entries from a hash, then make a list of those entries' keys -- and the result (a) isn't what I want and (b) seems sorta wonky. See README and (very small) bit of code in the attachment. If I have not understood something on this stuff...
