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,
