The basic question is, can you define the syntax of your "DD" or is it
something that is forced upon you? If it is the first, it is really
better to make it so it is simply directly Lua parseable. That does
not stop it from actually configuring a generator that generates some
code. Lua is also relative easy to sandbox, thus should not endanger
confidence.
