I would like to point out that the example code you refer to is meant to
illustrate a specific behavior of locks. It is *not* necessarily intended
to be an example of good style. As a "new gopher" I would avoid this idiom.
If you did use this, some significant commenting would be needed.
Also, what blog post are you referring to?
