Good day bros. I am trying to implement some sample code in mod MCE for implementing Strassen's algorithm for matrix multiplication. At the beginning of the subroutines is the following: 
######################################################################
+#########
 # * # * # * # * # * # * # * # * # * # * # * # * # * # * # * # * # * #
+ * # * #
######################################################################
+#########

my @p;

sub store_result {

   my ($n, $result) = @_;

   $p[$n] = $result;

   return;
}

sub configure_and_spawn_mce {

   return MCE->new(

      max_workers => 7,

      user_func   => sub {
         my $self = $_[0];
         my $data = $self->{user_data};

         my $tam = $data->[3];
         my $result = [ ];
         strassen_r($data->[0], $data->[1], $result, $tam);

         $self->do('store_result', $data->[2], $result);
      }

   )->spawn;
}

My question is about the my @p. This occurs after the completion of the main script, yet it is declared as a local variable so it is within the scope of the main script. It is referenced in sub store_result but is outside its scope. My debugger (Komodo) doesn't flag this as a problem, which it seems like it should. Does anyone know what's going on here? I have not used MCE so maybe it's something peculiar about it?
