Defect report: ref-qualifiers in partial ordering of non-static template operator members and non-members

Show all headers | View raw

Hi,

C++11 [temp.func.order]p3 says:

"If only one of the function templates is a non-static member, that function
template is considered to have a new first parameter inserted in its function
parameter list. The new parameter is of type “reference to cv A,” where cv are
the cv-qualifiers of the function template (if any) and A is the class of
which the function template is a member. [ Note: This allows a non-static
member to be ordered with respect to a nonmember function and for the results
to be equivalent to the ordering of two equivalent nonmembers. — end note ]"

This paragraph does not specify what kind of reference the new parameter
should be (and I can't see anywhere else in the standard which specifies
this). It seems to me that the standard should specify that the new parameter
shall be an rvalue reference if the non-static member function template uses
the&&  ref-qualifier, and an lvalue reference otherwise.

Thanks,
Richard
