My point was not about necessary ambiguity where precision is not attainable. It was about todays inability of the legal professions to write concise conditions within contracts or laws. E.g. as someone else said in this threat, there is useful ambiguity in requirements like: „within reasonable time“. But if you are enumerating a bunch of things and their relationships, ambiguity is often not what you want, but what you get without some clear syntax. In my experience it’s not uncommon to stumble upon legal texts like „a, b and c or d then …“. But what does that mean? Is this supposed to be „(a && b && c) || d“ or „(a && b) && (c || d)“? That’s stuff that could easily be clarified at times of writing by just using parenthesis. Or maybe using actual lists with one item per line instead of stupid csv embedded in your sentences.
