Hi!  I'm taking over someone's code and have found the following class
signature - it's been abbreviated considerably; over 46 vars get used!!:

class showapp (
  $amqp_host,
  $amqp_password,
  $amqp_port,
  $amqp_user,
.
.
.

  $queue_service_host,
  $queue_service_port,
  $redis_host,
  $redis_port,
  )
It looks like they thought that any hiera vars that were going to be used
in the template needed to be defined in the class signature (this isn't
right, is it?).
these vars are defined in hiera and are needed to populate a template
defined elsewhere in the class.    I'd rather not have to define every var
in my manifest, e.g.:
$amqp_host = hiera(showapp::amqp_host)

I think I'd rather have a hash defined in hiera that I can pull into my
class with one call, e.g.:
$showapp_data = hiera(showapp)
then use as a hash, e.g.
$showapp_data[amqp_host]

Is that the way to go?  Will it work?  Is there a better way?

If you're gotten this far, thank you, thank you, thank you!

Guy
