Thank you, something similar to what you suggested reduced the
atom size from 72 bytes to 40.

Just create a nested anonymous struct, like this:

Question:
**Where do I begin my consolidation of space within `Atom`?
Do I use
unions or variants?**
In this case, since you're already keeping track of what type
of data is being stored in an Atom, use a union:
