Hey, Not an iterator, but it works.
use strict;
use warnings;
use Scalar::Util qw(reftype);
use Data::Dumper;
my $oWkBook = {
students =>[
{fname=>'joe',lname=>'bloe',age=>'18'},
{fname=>'jill',lname=>'bill',age=>'16'},
],
teachers => [
{fname=>'joe',lname=>'sloe',age=>'38'},
{fname=>'jill',lname=>'sill',age=>'36'},
],
admins =>[
{fname=>'koe',lname=>'moe',age=>'58'},
{fname=>'dill',lname=>'mill',age=>'56'},
],
};
print reftype($oWkBook);
my @test = getScalars($oWkBook);
for (@test) {
$$_ .= "test";
}
my $link = \$oWkBook->{students}->[0]->{fname};
print $link;
$$link .= "test";
print Dumper($oWkBook);
print Dumper(@test);
sub getScalars {
my $it = shift;
my $type = reftype($it);
my @out;
if (defined $type && $type eq "HASH") {
for my $key (keys %$it) {
if (!defined reftype($it->{$key})) {
push @out, \$it->{$key};
} else {
push @out, getScalars($it->{$key});
}
}
} elsif (defined $type && $type eq "ARRAY") {
for ( @$it ) {
if (!defined reftype($_)) {
push @out, \$_;
} else {
push @out, getScalars($_);
}
}
} elsif (defined $type && $type eq "SCALAR") {
push @out, $it;
} else {
return \$it;
}
return @out;
}
Left some of my fumbling in there, you can feel free to ignore that part. ;)

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).
