Nice case, but sory to say, the error is in your code. The key attribute expects a single scalar, not a list:
#!/usr/bin/perl
use strict;
use warnings;
use Text::CSV_XS qw( csv );
my $file = "/home/me/Documents/www/files/data/Miscellany/Magic_items.t
+xt";
open my $fh, "<", $file or die "Can't open $file $!";
my $list = csv (
in => $file,
sep_char => '|',
headers => [ "item", 'seen in" ],
key => "item", # SCALAR, not LIST
);
use Data::Dumper;
print Dumper $list;
Should work exactly as you intend
I'll see if I can make a warning/error for this case
Enjoy, Have FUN! H.Merijn

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).
