Review comment:
Hmm, would the user ever want to pass a schema to force a cast? Though I
suppose that's redundant (either configure the scanner or pass a scanner
instead of a dataset).
I think a deprecation warning would be appropriate here (schema will only be
allowed when passing an iterable in the future).
