Best thing i could think of would be either an array, or using the var-value as filename within a tempfolder.
What are you heading for?
Might help to provide suggestions.

pod::abstract::buildnode
Pod::Abstract::BuildNode(3pm) User Contributed Perl Documentation Pod::Abstract::BuildNode(3pm)
NAME
Pod::Abstract::BuildNode - Build new nodes for use in Pod::Abstract.
SYNOPSIS
use Pod::Abstract::BuildNode qw(node nodes); # shorthand
my $root_doc = node->root;
for(my $i = 1; $i < 10; $i ++) {
$root_doc->push(node->head1("Heading number $i"));
}
print $root_doc->pod;
DESCRIPTION
For building a new Pod::Abstract document, or adding nodes to an existing one. This provides easy methods to generate correctly set nodes
for most common Pod::Abstract elements.
NOTES
Pod::Abstract::BuildNode can export two functions, "node" and "nodes". These are constant functions to provide a shorthand so instead of
writing:
use Pod::Abstract::BuildNode;
# ...
my @nodes = Pod::Abstract::BuildNode->from_pod( $pod );
You can instead write:
use Pod::Abstract::BuildNode qw(node nodes);
# ...
my @nodes = nodes->from_pod($pod);
Which is more readable, and less typing. "node" and "nodes" are both synonyms of "Pod::Abstract::BuildNode".
This shorthand form is shown in all the method examples below. All methods operate on the class.
METHODS
from_pod
my @nodes = nodes->from_pod($pod_text);
Given some literal Pod text, generate a full subtree of nodes. The returned array is all of the top level nodes. The full document tree
will be populated under the returned nodes.
root
my $root = node->root;
Generate a root node. A root node generates no output, and is used to hold a document tree. Use this to make a new document.
begin
my $begin_block = node->begin($command);
Generates a begin/end block. Nodes nested inside the begin node will appear between the begin/end.
Note that there is no corresponding "end" method - the end command belongs to it's corresponding begin.
for
my $for = node->for('overlay from <class>');
Create a =for node. The argument is the literal body of the for node, no parsing will be performed.
paragraph
my $para = node->paragraph('Pod text');
Generates a Pod paragraph, possibly containing interior sequences. The argument will be parsed as Pod, and will generate text and sequence
nodes inside the paragraph.
verbatim
my $v = node->verbatim($text);
Add the given text as a verbatim node to the document. All lines in the fiven $text will be indented by one space to ensure they are
treated as verbatim.
heading
my $head2 = node->heading(2, $heading);
Generate a heading node at the given level. Nodes that "belong" in the heading's section should be nested in the heading node. The $heading
text will be parsed for interior sequences.
head1
node->head1($heading);
head2
node->head2($heading);
head3
node->head3($heading);
head4
node->head4($heading);
over
my $list = node->over([$num]);
Generates an over/back block, to contain list items. The optional parameter $num specifies the number of spaces to indent by. Note that the
back node is part of the over, there is no separate back method.
item
my $item = node->item('*');
Generates an item with the specified label. To fill in the text of the item, nest paragraphs into the item. Items should be contained in
over nodes.
text
my $text = node->text('Literal text');
Generates a literal text node. You generally do not want this, you probably want a paragraph. Use this if you want to, for example, append
a word at the end of a paragraph.
pod
my $n = node->pod;
Generates an "=pod" command. Can be useful to force pod mode at the end of cut nodes.
Do not confuse with "from_pod"!
my $cut = node->cut;
Generates an explicit "=cut" command.
