  raise(Puppet::ParseError, "write_erl_config(): Wrong number of arguments " +
        "given (#{args.size} for 1 or 2)") if args.size < 1

  # Functions called from puppet manifests that look like this:
  # lookup("foo", "bar")
  # internally in puppet are invoked: func(["foo", "bar"])
  #
  # where as calling from templates should work like this:
  # scope.function_lookup("foo", "bar")
  #
  # Therefore, declare this function with args '*args' to accept any number
  # of arguments and deal with puppet's special calling mechanism now:
  if args[0].is_a?(Array)
      args = args[0]

  h = args[0] # hash
  s = (args.length == 2 && args[1]) || :pp # symbol
