I'm still salty about Specter[0] not being ~officially recognised as a necessity when using Clojure.

Data driven languages need simple & powerful transformation libraries. `get-in` is repetitive and tiresome to use.
Specter and it's ilk make transformations clear and simple.
No amount of planning or foresight negates the need for data transformation libraries.
