[Puppet Users] Overriding class parameters using a collector

Hello,

Is it possible to override parameters of a class using a collector?
(similarly to
https://docs.puppetlabs.com/puppet/latest/reference/lang_resources.html#amending-attributes-with-a-collector)

The following gives "Resource type cls doesn't exist" error:

class cls($arg="default"){notify{$arg:}}

node foo
{
  Cls <| |> {arg => "override"}
  class{'cls':}
}

It works if I change "class" to "define" though.


Thanks,


Vlad
