Puppet users - Jul 2012 - Ruby DSL parameterized classes and defaults

I''ve been reading the Docs on this, and its not very clear.

I want to have a parameterized class that takes arrays and objects as 
parameters.
I''m using puppet 2.6.16.

I define a hostclass like this:

hostclass :test, :arguments => { :param1 => "blah" } do

end

I call from Puppet DSL:

class {"test":

}

I get this as an error:

err: Could not retrieve catalog from remote server: Error 400 on SERVER: 
Puppet::Parser::AST::Resource failed with error NoMethodError: undefined 
method `safeevaluate'' for "blah":String at 
/data/puppet/nbenns/modules/atg/manifests/init.pp:56 on node <removed>

If I add the parameter in its fine.

If :arguments => { :param1 => "blah" } isn''t used as
:arguments => {
paramname => default value }
then what is it?
the documentation isn''t clear at all on this.

Thanks.

Try using it in the other way:

include test

rather than in the parametrized way.
