Hi,

First of all, please avoid the word fields as it is very confusing in OO. (pseudo hashes, etc...) as they are not lexically scoped (don't use my with fields).

Second, I see no inheritance operator in your classSome::Package::Sub. It misses the line 

use base qw(Some::Package);

Third: The line my %fields is totally useless in the package Some::Package::Sub, as it is lexically scoped, and only consultable from with the package itself. I would suggest to create an init subroutine, and call this from inside the new statement. f.e. 
sub new {
  my $proto     = shift;
  my $class     = ref($proto) || $proto;
  my %args      = @_;
  bless($self, $class);
  $self->init();

    foreach my $arg (keys(%args)) {
      $self->$arg($args{$arg});
    }
  }

And in the Some::Package::Sub 
sub init {
   my $self=shift;
   $self->{_permitted} = \%fields;
   #... and add the other fields also
  };

It least, this is the way I would do it, but since I am not perfect....
