I'm hoping somebody can help me interpret what's going on in the following line of code:

 my @refs = @allrefs[ sort {$a <=> $b} values %uni_refs ];

As far as I understand,  sort {$a <=> $b} values $uni_refs will sort $uni_refs by its values, numerically descending. Is this a correct interpretation?

Assuming I'm correct so far, what does it then mean to have @allrefs outside of the square brackets containing the sort?

Help greatly appreciated.
