Yes? Do you foresee this being a typical thing to write in configuration files? If we're being pedantic, as you were in your comment, "close to Turing complete" is not really a very precise term, is it? When you have an issue, at least be explicit about it rather than just snarky. (See also Gabriel's other comments in this thread; not that I know or have any affiliation with him.)
