The problem with this article is that the examples suggested never happen.
Once in a while with dynamic languages you come across a "librarian" who likes to use the arcane language features. Perhaps more often, if you use Java, you will encounter code where a lot of AbstractWhatTheFracktory design pattern abuse is going on. However you will never, ever find the "ascetic" who rewrites the zipcode-padder using lambdas.
Sadly, most of the time you just see the typical egregious dailyWTF mess.
Of course you never see people use the y combinator to write a string padding algorithm. But do you ever see people overuse metaprogramming or abuse open classes?
