=head1  ArrayRefs of types

this feature was added to Moose sometime after 0.17 which shipped with etch

please uncomment the lines below when our system have migrated to lenny or a later Moose

Moose::Util::TypeConstraints->create_parameterized_type_constraint ('ArrayRef[ReadableDir]');
Moose::Util::TypeConstraints->create_parameterized_type_constraint ('ArrayRef[WritableDir]');
Moose::Util::TypeConstraints->create_parameterized_type_constraint ('ArrayRef[ReadableFile]');
Moose::Util::TypeConstraints->create_parameterized_type_constraint ('ArrayRef[WritableFile]');
Moose::Util::TypeConstraints->create_parameterized_type_constraint ('ArrayRef[WritablePath]');
Moose::Util::TypeConstraints->create_parameterized_type_constraint ('ArrayRef[File]');
Moose::Util::TypeConstraints->create_parameterized_type_constraint ('ArrayRef[Dir]');

then you can delete the types defined the 'old' way below

=cut

subtype 'ArrayRef[ReadableDir]'
=> as 'ArrayRef'
        => where {
                foreach(@$_)
                {
                        return unless -d $_;
                        return unless -r $_;
                }
                return 1;
        }
=> message { "One of the directorys in the array is not readable!" };

subtype 'ArrayRef[WritableDir]'
=> as 'ArrayRef'
        => where {
