If I understand your question, I think you are looking for information available in caller. You don't want to know who called you, but who called something that called you.
use strict;
use Carp;
trace('foo');
trace('bar');
func();
sub func
{
trace('in func');
}
sub trace
{
my $string = shift;
my ($package, $filename, $line, $subroutine, $hasargs,
$wantarray, $evaltext, $is_require, $hints, $bitmask) = caller(
+1);
if($subroutine)
{
print "[$subroutine]: $string\n";
}
else
{
print "[**IN MAIN**]: $string\n";
}
}
__END__
[**IN MAIN**]: foo
[**IN MAIN**]: bar
[main::func]: in func
"Look, Shiny Things!" is not a better business strategy than compatibility and reuse.

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).

or How to display code and escape characters
are good places to start.
