66. Visibility of default args vs overloads added after using-declaration

Section: 9.3.4.7  [dcl.fct.default]     Status: NAD     Submitter: Mike Miller     Date: 6 Oct 1998

Paragraph 9 of says that extra default arguments added after a using-declaration but before a call are usable in the call, while 9.9 [namespace.udecl] paragraph 9 says that extra function overloads are not. This seems inconsistent, especially given the similarity of default arguments and overloads.

Rationale (10/99): The Standard accurately reflects the intent of the Committee.
