No, my reply was to @garrison who is using the terminology differently. I don’t really understand either use.
OK, definition has expanded a bit, but nothing I haven’t already heard. What I haven’t heard is how/why this tooling in particular does those things more than other validation patterns.
Yes, sorry, I should have been clear that I understand the concept of lenses and traversals and they seem like an interesting pattern but my question is more directed that the (implicitly positive) rhetorical use of “declarative.” It doesn’t really help me understand why I should consider this pattern over ones that are simply more familiar to me. Again, not specifically a problem in your presentation, I have never found uses of this term very compelling.
