The issue is that we're generating ProjectSet nodes instead of Result
for the top-level nodes - but we currently assume that ProjectSet nodes
actually contain sets. I'm tentatively in favor of generating proper
Result nodes in this case, rather than allowing this in ProjectSet - on
the other hand, it works after removing that Assert().
Tom, do you have an opinion?
