  • When we first started teaching Perl there was the temptation to show off all the things Perl could do. So we showed off $" and $,. That lasted for about 3 courses. Then we decided that the students really should learn to use join instead.

    Our course notes [] deliberately avoid mentioning as many of the bad-old ways as possible, although we still start the file chapter with ugly, old-style file handles because they are so overwhelmingly prevalent (see the first few actual examples in perldoc -f open and perldoc perlopentut).

    I probably wouldn't buy such a book for myself; but I'd probably have it as one of our strongly encouraged books for our students and clients. We are responsible for about 30 Programming Perl and 40 Perl Best Practices book sales each year. (This only works if you publish with someone our book supplier has agreements, which is essentially Manning and O'Reilly).
