Review Comment:
> Alright, so the behaviour is actually depend on `array` itself. I think we
can use `make_array` in this case.
Ok, I'll roll back to `make_array` first.
> current API expects `map(vec![make_array(vec![lit("a"), lit("b")]),
make_array(vec![lit("1"), lit("2")])])` a slightly better API is
`map(vec![lit("a"), lit("b")], vec![lit(1), lit(2)])`
I'm not very familiar with the data frame implementation. Curiously, does
the API for data frames also use the UDF `map`? I think the UDF is a logical
layer function, but we don't have a corresponding logical expression for `vec!`
other than `make_array`.
