Huh? While PCL is a great introduction text with practical examples, I doubt its suitability as ANSI CL standard compliance benchmark; it surely wasn't meant as such. Why not use Paul Dietz's ANSI test suite?

The tests against Seibel's book were meant as a quick way of assessing the major differences with ANSI. But books like this are also a way of exercising the part of the language that is used in practice. We do mean to follow up with more in depth investigations, such as running a test suite like Dietz's.
