It seems suitable to me for a system that is strictly defined with relation to some domain, especially when that domain is based on fairly immutable concepts, e.g. a mathematical foundation. Low chance of code intent changing means literate docs will likely remain fairly stable as well.

@fellshard Yeah... but I don't think I've ever worked on a system that is like that... the real (business) world seems very fluid in terms of requirements and domain rules... 👀

Likely not a use case for the highly mutable biz world, yep :)
