Dear Monks,
I have an array of hash-references and want to retrieve a single hash from it.
There is a primary key in each hash. This is done by the following code:

$hashref=grep {has_the_right_primary_key($_)} @hashes;
%hash=$$hashref;

I wonder if I can get the hash instead of the hashref with a single line.

In reply to Dereference array-elements by very empty
