Yes, it's called ... caller!

 From perldoc -f caller

        caller EXPR
                With EXPR, it returns some extra information that the 
                uses to print a stack trace.  The value of EXPR 
indicates how
                many call frames to go back before the current one.

                    ($package, $filename, $line, $subroutine, $hasargs,
                    $wantarray, $evaltext, $is_require, $hints, 
$bitmask) = caller($i);

So, is there some reason why element[3] in the above list won't work 
for you?
