3.4.2 Argument-dependent name lookup [basic.lookup.koenig]
1 When an unqualified name is used as the postfix-expression in a func-
tion call (_expr.call_), other namespaces not considered during the
usual unqualified lookup (_basic.lookup.unqual_) may be searched, and
namespace-scope friend function declarations (_class.friend_) not oth-
erwise visible may be found.
Note that it only refers to namespace-scope friend functions (which
eliminates member functions)

Good questions for comp.std.c++, indeed...
