Ah! I didn't realize this was the case! Yes, that's how qualified
lookup for namespace members works; if there's a direct declaration of
the searched name in the nominated namespace then any using directive
contained therein is ignored (for the purpose of looking up the name).
Strictly speaking, the standard refers that rule to user-declared
namespaces, not std. However... :-)
