I made an artificial neural network module, in which lots of piddles are used to store the connection weights. I need to store those weights to store the network state. Currently, I convert piddles into perl arrays using following way: 
my @scalar;
my $size = $piddle->getdim(0);
for (my $i=0; $i<$size; $i++) {
  push @scalar,$piddle->at($i)
}

and dump a very large perl AOA into string using YAML.
However, this implementation is very slow, especially when there are ten thousands of piddles to work through. So, how can I dump them with high efficiency?
