If this is expected/documented behavior of the C++ library, I don't think we
need a test for it at all in R.

of the error with the "/" next to the column name?
I think that's probably intended, though you could confirm. My guess is
that's how the reader will handle named references of nested structs: suppose
(or test for yourself) that "third_col" had a value like `{"subcol1": 4,
"subcol2": "a"}`, and you mis-typed subcol2, it would probably say
"/third_col/subcol2" like a file path. If that's *not* the case, then it seems
like a bug.
