Right now fry doesn't support "frying" into sequences that aren't quotations,
so this works:
'[ [ _ ] ]
But this doesn't:
'[ { _ } ]
We have a plan to fix this as it turns out I was talking about this issue a
couple days ago with someone. I'd like to make this fix since a lot of people
hit this limitation at some point.
Best,
John.
