Thanks, I'll have a look!
For me the case is I have a universe of binary format descriptions, and an associated family of in-memory representations of those format descriptions:
Format : Type
Repr : Format -> Type

Ahh will have to ponder the implications of that but that’s useful knowledge to know. Am currently sketching it out using Idris 2 as a logical framework which doesn’t yet keep me honest bout such stuff. Maybe I should switch to Agda 😅
There’s might be some exotic use cases of meta-formats that can describe other formats, but from that I think I can start to get an inkling about why you’d need to be careful about this stuff.
