Matthias Friedrich updated CRUNCH-97:
-------------------------------------
Attachment: CRUNCH-97-Tokenizer-v1.patch
Here's how it would look with Tokenizers. This is just a demo, I would clean it
up if we decided to go this way. I'd also have to design a nice call syntax for
Parse with tokenizers.
What I don't like about it: It makes nested collections harder to implement
(see the ugly hack for Extractors.xcollect()). We also have to pass column
positions to ExtractorS - that's the price we pay for flexibility.

> We should make it a bit easier to parse delimited text files into specific
> data types (e.g., ints, floats, etc.) or combinations of types-- e.g., pairs
> of strings and ints, a Tuple3 of booleans, etc.
