Hi, Taro Nishino.
Yes, I was perhaps the first to transplant json to Perl as you said.
I appreciate your hearty review!
This review will be basically identical to my review regarding JSON.
If my memory serves me correctly, the author is the first person to have transplanted json to perl. Makamaka-san, is my recognition all right?
For the reason above, I'd like to compliment the author on his achievement.
