Hey there,

I have the following class that defines an array:

class iptables::hyperion {
  system_ips [
    'ip',
    'ip',
    'ip',
    ...
  ]
}

To use this variable in a template, I'm setting it to a 'local'
variable in the node definition:

node 'mynode' inherits basenode {
  include iptables::hyperion
  $system_ips = $iptables::hyperion::system_ips

  class { iptables:
    fragments => [ 'hyperion.erb']
  }
}

I can then access and use $system_ips in a template for that node (in
this case, 'hyperion.erb'). Does this fit a common pattern? I know
that in a template you can use 'scope.lookupvar('var')'. Should I be
using said function in the template to access
$iptables::hyperion::system_ips, instead of reassigning it in the node
definition?
