There is a discussion about that here: [Union splitting vs C++ - #13 by ChenNingCong](https://discourse.julialang.org/t/union-splitting-vs-c/61772/13)

(see some previous posts).

I don’t know if there are specific proposals on how that can be improved, but there seem to be inherent limitations relative to the approach taken in static languages.
