use Data::Dumper;
my $up = Data::MessagePack::Unpacker->new;
open my $fh, $data or die $!;
my $offset = 0;

}
=head1 DESCRIPTION
This is a streaming deserializer for messagepack.
=head1 METHODS
=over 4
=item my $up = Data::MessagePack::Unpacker->new()
creates a new instance of the stream deserializer.
=item $up->utf8([$bool])
sets utf8 mode. true if I<$bool> is omitted.
returns I<$up> itself.
If utf8 mode is enabled, strings will be decoded as UTF-8.
The utf8 mode is disabled by default.
=item my $ret = $up->get_utf8()
returns the utf8 mode flag of I<$up>.
=item $offset = $up->execute($data, $offset);
=item $offset = $up->execute_limit($data, $offset, $limit)
parses unpacked I<$data> from I<$offset> to I<$limit>.
returns a new offset of I<$data>, which is for the next <execute()>.
If I<$data> is insufficient, I<$offset> does not change, saving
I<$data> in internal buffers.
=item my $bool = $up->is_finished();
is this deserializer finished?
=item my $data = $up->data();
returns the deserialized object.
=item $up->reset();
resets the stream deserializer, without memory zone.
