I don't see a gain here for goto sub { ... } over do { ...; return }. You still have the same size call-stack. I think I'd mark this down as being clever for clever's sake.

Now, if you decided to implement continuation passing style with this: 

sub cool {
  my $return = pop; # get cps value
  my $p1 = shift;
  my $p2 = shift;
  ...
  ...
  if ($condition) {
    @_ = ($new, $arg, $new_return);
    goto &$return;
  }
}

Then I might be impressed.
