Talk:Perl Programming/Hash variables

Confusing example (without explanation) of the sorting of hashes: The section here https://en.wikibooks.org/wiki/Perl_Programming/Hash_Variables#Hash_of_Hashes_of_Hashes introduces an example of printing hashes but the reader might immediately wonder what is going on there. Well yes, by using "sort keys" the (sorted) output seems reasonably correct. On the other hand, the reader does see 3 different ways of assignment/output: 1. assignment (FIRST, THIRD, SECOND), 2. sorted output (FIRST, SECOND, THIRD), 3. Dumper output (THIRD, FIRST, SECOND). This is not clear at all, i.e. why the output of Dumper is the way it is.

I would suggest, that we at least add a note why there is this difference (i.e. the output of Dumper is neither sorted, nor always in the order it was assigned to).
