Re^4: Sorting an array of anonymous hashes with named hashes using hash value by haukex (Archbishop) on May 07, 2016 at 12:22 UTC
Hi nysus, There is one caveat to the AM's code: because hash ordering is random, `( values %$_ )[0]` picks a random value from that hash. So if I change your example data structure like so: `$places->[0]{123}{name} = "Alpha";`, the sort will give random results. So if you use that sort method, make sure that you know each hash at that level only has one key. Hope this helps, -- Hauke D	[reply] [d/l] [select]
