Personally I think the constitution should contain only the very basic meta law. What is a law, what do we mean with rights, that the country is divided into states, what congress is etc.. In a language for this forum, something like a lisp kernel or a set of axioms. Abortion, gun rights, and so on are actual legal content and should be strictly separate laws. From the perspective of a software engineer, many legal bodies seem poorly organized (especially in countries with Anglo-Saxon heritage).
