It helps people understand what's being checked.

On an unrelated topic, the patch works by replacing the normal use
list with a std::list. To be really complete, it should leave the
normal use list in place, so that it the normal use list code
continues to be tested in XDEBUG builds. A parallel std::list
could be maintained for consistency checking.
