> "I would say, the code is put into lines naturally"
I beg to differ. I've being reading pg's code and feel quite comfortable saying that his natural coding would have a line break in the example above - as would any of ours (unless you are unaware of the two spaces required for code on this forum - haha :)
Not a criticism of pg or his code. I think most the submissions to Norvigs site contain code where people are removing "natural" line breaks.
"Perhaps we should stop at 15 lines before we start getting unreadable code :) !"
speaks the truth.
I don't think there's any real value in creating a table ranking languages by line numbers. I do think the code pg produced does demonstrate how pleasant arc is to read while being very short.
