Bugs

I just bought a big and expensive programming book at Powell's, from MIT Press, and in one of the first meaningful code sample, in the very beginning I read:

#define PI = 3.1592654

WTF!!! There are 2 bugs in this line, and I paid 80 bucks for the book!

Btw I am staying in Portland until next Sunday, so if you are around plz give me a shout..
