I dunno, with years of experience in OO (ruby for the past 7 or so, Java before that), this still definitely hits home.<p>I don&#x27;t agree with the commenter that suggests these suggestions are harmful on code written in OO style -- although they specifically say code written in &quot;Java&#x2F;.Net&#x2F;C++&quot; style; maybe?  But not ruby&#x2F;smalltalk&#x2F;ObjC style.
