When writing an AUTLOAD function it commonly looks like 
sub AUOTLOAD
{
  my $fn = something_clever_returning_fn_reference;
  goto &$fn;
}

this "magic" goto makes it look like the AUTOLOAD never happened by overwriting the call stack. My question is how to do this for methods. You could do 
sub AUOTLOAD
{
  my $self = shift;
  my $m = something_clever_returning_method_name();
  $self->$m(@_);
}

but the call stack would still show the AUTOLOAD So, I thought of this 
sub AUTOLOAD
{
  my $self = $_[0];
  my $m = something_clever_returning_method_name();

  my $sub = $_[0]->can($m) || $_[0]->can("AUTOLOAD");

  die "Can't call $m on $_[0]" unless defined($sub);
  goto &$sub;
}

I don't see why this would be wrong. Are there any drawbacks to this method? I've never seen it used before. Why do all the tutorials show how to use the magic goto &$sub for functional programming but never for OO?
