Josh Wills commented on CRUNCH-97:
----------------------------------
Re: the order in which fields are extracted, it seems like we should have a
swap() method in PTables for that, which would be useful beyond just text
parsing.
I respect the -0, although I like Scanner as a balance between regex and
split-style parsing. The Extractor interface and the Parse code are independent
of any particular tokenizing implementation, so if there's a better way to do
it, we do have the freedom to experiment.

> data types (e.g., ints, floats, etc.) or combinations of types-- e.g., pairs
> of strings and ints, a Tuple3 of booleans, etc.
