Allow non-stratego data types to be stored as custom unit and custom global analysis results.
These data types probably need to support serialization and deserialization.

(I tried to use the https://github.com/usethesource/capsule immutable collections library.)

Workaround: convert the data structure to an aterm before passing it to NaBL2, and converting it back to your own data structure when getting it back from NaBL2.

I did a small experiment to see if this could be supported. It turns out that even on the built-in indexed sets, some operations such as putting annotations fail. Supporting this would create a lot of special cases. Furthermore, excessive use of non-Stratego datastructures sounds like a smell to me. This may be better fixed in a different way than hakcs to support wrapped non-terms. Therefore, I won’t fix this.
