I have an AoH that looks like this: 
my @aoh = ( 
    {k0 => 'v0' }
  , {k1 => 'v1' }
  , {k2 => 'v2' }
  , {k3 => 'v3' }
);

I want to pull out the value of the element with key k2. The nicest way I can think of to do this is something like 
$val = [grep {(keys $_)[0] eq 'k2'} @aoh]->[0]{'k2'};

[download]
But that's kind of disgusting. Is there a nicer way?

Update: Corion pointed out that I could just convert the AoH into a hash given the keys are unique and have a single value each. Like:

my %h = map {%$_} @aoh;

## now its just:
say $h{'k2'};
