I recently learned from Darin Adler on the webkit-dev list that there are a few
more "unwritten rules" regarding "using" statements in header files.  Namely--

(1) "using namespace" directives are unacceptable only if in the global scope
(the guidelines say they are always unacceptable).
(2) The rules should probably apply not just to "using namespace" directives
but also to "using" declarations.
(3) Statements of the form "using WTF::..." are exceptions.

Also, the coding style page does not validate.

A patch is forthcoming.
