I'll leave it here as is the apparent preference of the community as testimony that just because you haven't encountered the name of something, that you haven't been unwittingly using it for years.
That's what I think is the great thing about design patterns. They give names to all those things that we've been doing for years. This makes it a lot easier to talk about the concepts in question.
By definition, a design pattern cannot be new. It has to have been done several times before people can spot it as a pattern :-)
Getting by the fact that I was arguing against the example given rather than the definition itself.
Apologies for the confusion caused by my poor nomenclature.
