I wasn't trying to get into the specific technology. The Julia still needs to be parse, and while Yaml has them separate, CUE does not (which is where I write things like this and have building blocks for lenses [1], in the conceptual sense)
In the conceptual sense, or at least an example of one, lenses are about moving data between versions of a schema. It sounds like what you are describing is capable of this as well? (likely among many other things both are capable of)

Yes functional lenses are very good at transforming between between schematas.
You can think of it as an functional programming based embedded domain specific language for transforming immutable data structures into each other. Sure there are other ways to do it but its like generalized map/filter/reduce class of functions vs doing the same imperatively by hand or in other ways
hmm, that makes it sound closer to CUE, where all values are immutable
CUE is in the logical family with Prolog and is not Turing Complete
