Stuart, Excellent point about delimiters, parsing CSV is much more sophisticated than my simple s-exp.
However, since you're writing a parser you've worked with strings a lot :) I use something like str-take/str-drop all the time in my parsers. So if you could answer a few questions... 1. Would str-take/drop make your code any easier to write? 2. Would str-take/drop make your code any easier to maintain? 3. What would you add (or remove) from the two functions to help your parsing? 4. If str-take/drop were part of a standard library, would you be more likely to use them? 5. If str-take/drop were part of a standard library, would you be more likely to write about them in your book :-p (Excellent work, btw! Can't wait for print version!) Happy Hacking.
