Try `Union{Nothing, Some{T}}` instead of `Uninitialized`?

EDIT: ah, nevermind, same problem.

If anyone is following along, I opened a PR for the `Ref` implementation that doesn’t force `mutable` [https://github.com/KristofferC/LazilyInitializedFields.jl/pull/1](https://github.com/KristofferC/LazilyInitializedFields.jl/pull/1). It’s a bit more complicated than I liked due to the reasons given above.
