  • You're definitely right about the whole sharp tools vs professional stuff.

    I wouldn't mind seeing a danger-factor or something for the features discussed.

    There's a lot of stuff that is in the sharp categories I only find I need once every few years (flip flop conditionals, the @- and \G stuff, and so on).

    They are badly needed when you need them, but you need them SO rarely.
    • Flip flops! Damn it, I didn't put that in the book. I knew I was missing something. :)

      I've have to think about how to mark some things with a big caution sign. O'Reilly has marginal glyphs for that sort of thing. That means that I'll have to go back through the book and figure out which things are too pointy.
      • Yeah, I was surprised that flip-flops weren't in there... once Adam mentioned them. I use them very rarely, but it's always "hilarious" when I look at six or seven lines of code and realize, "Hey, that's a one-liner with ..."

        The only other two omissions that I thought were notable were in the error handling chapter. I was surprised you didn't mention Exception::Class, but that's largely because I use it so extensively. I was much more surprised that you didn't mention SIG{__DIE__} at all.
