23:23:10jasomIs there a library that makes a non-seekable stream (somewhat) seekable by adding buffering on top? I'm thinking something that guarantees always allowing seeking back N elements (up to the beginning, where N >> 1 and is possibly configurable)
23:28:16mfianoA Gray stream wrapper for that would be only a couple lines of code not even worth a library
3:30:55jasommfiano: it's not the number of lines of code, it's how long it takes to write the lines of code. I've written something similar before and I had some subtle bugs with my first implementation.
8:53:20moon-childare there guidelines about when to use rplaca/rplacd vs (setf (car/cdr))?
