I am also interested in this, and I believe many others would be as well. I list some packages that target this particular problem below for reference

- [https://github.com/ahwillia/CatViews.jl](https://github.com/ahwillia/CatViews.jl)
- [GitHub - rafaqz/Flatten.jl: Flatten nested Julia objects to tuples, and reconstruct them later](https://github.com/rafaqz/Flatten.jl) ([Discourse ann.](https://discourse.julialang.org/t/ann-metafields-jl-and-flatten-jl-packages-for-writing-composable-models/12849))
- [https://github.com/rafaqz/Nested.jl](https://github.com/rafaqz/Nested.jl)
- [https://github.com/simonbyrne/PackVec.jl](https://github.com/simonbyrne/PackVec.jl)

I might attempt at some implementation of packing/unpacking the `Zygote.Grads` type, which perhaps would be well received in the Flux repository.

If you made any strides forward on this problem I would be interested in learning from your experience. I will post here once I have a working solution.
