I think computer science, by and large, is still stuck in the Modern age.

It won't be covered in the book. The source code has to be useful for something, after all.

Sometimes I wish I could put an expiration date on my quotes.

As pointed out in a followup, Real Perl Programmers prefer things to be visually distinct.

Even if you aren't in doubt, consider the mental welfare of the person who has to maintain the code after you, and who will probably put parens in the wrong place.

Computer languages differ not so much in what they make possible, but in what they make easy.

The choice of approaches could be made the responsibility of the programmer.
