We need to use unless value.is_a?(String) || value.is_a?(Array) rather than klass = value.class unless [String, Array].include?(klass) because the klass version enforces type checking which is too strict, and does not allow us to accept objects wich have extended String (or Array). For example, generate() function now returns Puppet::Util::Execution::ProcessOutput which is just a very simple extension of String. While this in it's self was not intentional (PUP-2306) it is not unreasonable to cope with objects which extend Strings
