The Temptations of Symmetry

by martin on October 26th, 2010

Kevlin Henney wrote a white paper on patterns in Java called The Temptations of Symmetry. Here he suggests that software designs should be biased toward symmetry because symmetric designs tend to be simpler and hence easier to use. The paper includes sections on Returning What You Borrow, Not Returning What You Didn’t Borrow, Fault Injection, and Encapsulating What You Borrow. You can download a PDF version of the document from the following link:
