Thanks, that is interesting to hear! If the original phrases are comprehensible, I need to work a bit on my skills...

BTW: i just noticed the book is really a moving target, as i cannot find the original text anymore.

Anyway, the vanished text under chapter 1, section 'The Default Scalar Variable' described the predeclared variables $a and $b, and reasoned that $_ could not be used in sort() because sort() 'must process the elements of its list two at a time'. This is correct of course (the elements are just not necessarily neighbors), but the wording suggested to me: sort() iterates on adjacent elements pairs of its list.

Replies are listed 'Best First'.

    Oh, that does sound like it was confusing. Misunderstandings like this is why more documents need version control!
