This is an embarrassingly newbie question, but I have a mental block when it comes to references. Given the following simple data structure, how do I get a slice of the name data?
$household = { 23 => { last => 'Smith', first => 'Mary' },
22 => { last => 'Jones', first => 'Bob' }
};
Here's my newbie code that works:
my $key = 23;
my $person = $household->{$key};
my %name = %$person;
my @slice = @name{'first', 'last'};
How do I turn this into a one liner?

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
