Gabriel Reid commented on CRUNCH-97:
------------------------------------
I don't have any direct use or need for it right now, but I do have the feeling
that something like this is a really useful addition to Crunch, so I think it
would be a shame to close this out now. I'm pretty indifferent about the
Scanner vs Tokenizer discussion, but I don't have much context to base an
opinion on for now.
In any case, even if this would be primarily a help for prototyping, I think
that that is more than enough reason to include it. It's a similar situation to
reflection-based Avro -- it might not be what you want to use in production,
but it's incredibly useful for quick iterations in development. In any case,
I'm very much in favour of adding this (in one of its incarnations) to Crunch.

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