Boxes and underbars are awkward, and indenting can get all too easily sloppy. Imagine you're showing someone Gabriel's W...

This is not another I-hate-all-those-parens whinge whinge whinge posting. I use GNU emacs and SLIME, and even long before that I had made my peace with '(' and ')' when I sat at the computer. Contrary, I have found that when writing out even slightly hairy code on paper or at a whiteboard that I did...

This is e-lisp, not scheme or common lisp, I really don't expect homework. How about a little less evasion and snarkiness. In e-lisp, use the (nth ...) built-in function.

I'm not so sure I'm happy about seeing flatten as a necessity here. While I recognize a place for programming paradigms (e.g. functional programming), I think we do others a disservice by promoting them in too doctrinaire a fashion. For a tree where there are few unique leaves, the suggested algorit...

While the code below is undoubtedly an ugly vile hack, this is what I came up with on the spur of the moment. One things that makes me a bit unhappy aside from the fixed length buffer and the sloppy error handling* is that I'm not completely comfortable with read in this context. I'm not sure it's a...
