      If you want _all_ hashes serialised as maps then you can redefine
      SOAP::Lite's internal methods with something like this:

      *SOAP::Serializer::encode_hash = \&SOAP::Serializer::as_map;

      It causes a '... redefined' warning but otherwise seems to work.

      The other way is to explicitly type each hash that you want
      serialised as a map as shown above. You might also be able to bless
      each hash into your own class and then provide a serialiser for
      that class which produces a map. Somehting like this:

      package myType;

      sub new {
      my ($class, $value) = @_;
      bless $value, $class;

      package main;

      sub SOAP::Serializer::as_myType {

      my $h1 = myType->new({ ...});

      Not sure how you want arrays to be serialised but I would guess that
      the same approach would apply.
