I was reading this article called Contract Programming 101, when I ran into this little gem:
Note: the term Design By Contract was trademarked in 2003 by Dr. Meyer, so all the little free software pixies are dropping the term like a hot coal. The latest favoured term is Contract Programming, as suggested by Walter Bright in 2004 and used in the recent proposal by Thorsten Ottosen and Lawrence Crowl to the C++ standards body.That is not cool!
