    The reason for this question was this: I found a tretris game online written in perl. I read through the code, and it was very interesting how they used transformations. It was quite clever...check out this link: http://docstore.mik.ua/orelly/perl2/advprog/examples/GUI/tetris.pl.

      In light of the consideration: "Is that a link to pirated content?"

      The code (tetris.pl) is part of the content of the book Advanced Perl Programming (Chapter 15: GUI Example: Tetris).

      O'Reilly freely provides example code from the book in both .tar.gz and .zip formats. This specific script is in examples/GUI/tetris.pl.

      Be aware this book was published in 1997. While I couldn't find a reference to a specific Perl version used for the code examples, it must be earlier than Perl v5.5 which was released in 1998 (see perlhist).
