def parse_args(args)
  # Functions called from Puppet manifests like this:
  #
  #   hiera("foo", "bar")
  #
  # Are invoked internally after combining the positional arguments into a
  # single array:
  #
  #   func = function_hiera
  #   func(["foo", "bar"])
  #
  # Functions called from templates preserve the positional arguments:
  #
  #   scope.function_hiera("foo", "bar")
  #
  # Deal with Puppet's special calling mechanism here.
