There's some truth to this, since some design patterns can simply be implemented "for good" in a sufficiently powerful language, but I don't find it's true in general. Unfortunately, it has become something of a thought-terminating cliché. Some common design patterns are so flexible that if you really implemented them in full generality as, say, some library function, its interface would be so complex that it likely wouldn't be a net win.

Then I would say you have not arrived at the optimal solution. Keep looking.
