Jacques Nadeau commented on ARROW-7779:
---------------------------------------
It feels like a mistake to think of dictionary-encoding as a type. I don't
think the example you gave was in the spirit of what we intended when we
defined dictionary encoding. Why not just say it isn't supported?
In this example we'd say: if you want to dictionary encode the lists, you can't
dictionary encode the values in the lists as well. At least for now.
