This is annoying when you deal with time series where it is common to have text files with a mix of dates, timestamps and numbers. You can write generic code to deal with ints and floats, but have to special-case anything time related.
Generic code that uses a Callable[[str], ...] instead of a type works fine with a class method.
column1.parser = int column2.parser = float column3.parser = datetime.parse_iso column4.parser = json.loads
It is *very slightly* more complex than a model that needs the type also for some reason and has the type pull double duty as the parser... but why do that?
