Though CSV is favored for 'simple' lists, a JSON value will be used if
it parses without error. This assumes that it is extremely unlikely
that something that parses as JSON would be intended to be parsed as
CSV, e.g. `["a"` and `"b"]`, as opposed to `a` and `b`. If
parsing/conversion fails, it is treated as if it was a CSV.
Since the CSV approach required processing of each element, code was
refactored to reuse the same logic used for individual non-typed
variables.
