That should be fine, although the assignment of $sub looks broken as the calling object doesn't have the $m method defined (unless the $m method is created in the AUTOLOAD call), otherwise AUTOLOAD wouldn't have been called. Also unless you're doing something really clever with $m that will loop forever as the calling object has AUTOLOAD defined, and without the $m method defined $sub will always end up pointing to the AUTOLOAD method and calling itself in the goto. Here's my take on AUTOLOADing methods 
sub AUTOLOAD {
  no strict;

  (my $m = $AUTOLOAD) =~ s{.*::}();

  *$m = make_method_here()
    if $m =~ /fulfils some condition/;

  croak "AUTOLOAD: can't access method $m";
    unless defined *$m{CODE} and $_[0]->can($m);

  goto &$m;
}

But as far as calling goto with a method name having left @_ intact, that nicely emulates a method call. The drawbacks would be that it'll be slow, and it's always a bit contentious dynamically creating/accessing methods via AUTOLOAD when quite often the likes of Class::Accessor will suffice (but as always, it's somewhat of a rule-of-thumb decision).
