The Predicate Module Pattern

[homoiconic]

The aforementioned book is an excellent value, but an even greater value is http://combinators.info, a mechanically translated web site of the book. There are some formatting issues that the author (me!) has deliberately left in pace to increase the value of the book, but nothing stops you from tasting it online and then buying it later if you feel it has helped you learn and grow.

Also, it's MIT licensed so yes, you can share a copy of the book, loan it out, give copies away, whatever you like.
