Well this is far beyond what the OP wanted!

And your $return->() if $return clause makes it quite esoteric ...

> Try do same with "goto"

... FWIW!

use strict;
use warnings;
our $target="";

sub rec {
  my ($i) = @_;
  $i++;
  print "i=$i $target\n";
  if ($i == 3) {
    target($i);
  }
  if ($i == 5) {
    goto $target if $target;
  }
  if ($i == 7) {
    return;
  }
  rec($i);
}

sub target {
  local $target="TARGET";
  rec(shift);
 TARGET:
}

rec(0);

__END__

i=1 
i=2 
i=3 
i=4 TARGET
i=5 TARGET
i=4 
i=5 
i=6 
i=7

As I said it's only an abstraction of the goto mechanism!

Good night! =)
