"Baby" Perl versus "Bad" Perl
And to think I decided not to try to write a Perl book a couple of years ago because I was scared the code wouldn't be good enough. :)
On the OT of martial arts. I was a guest student at a Goju school, my background is mostly Taekwondo. One of the senior students, who I outranked slightly, chatted me up, commenting how he found Taekwondo practitioners were the easiest to beat at tournaments. I said something like, "Oh. I see," and never said anything else about it to anyone. A couple days later the head instructor calls me into his office and says, "I heard you had a little trouble with ______. I completely apologize and it's been taken care of."
There are good schools in all arts and they invariably have that kind of instructor; one who knows everything that's going on and won't tolerate disrespectful BS. You should go back if you can find a school like that.
