--- Comment #3 from Patrick Palka <ppalka at gcc dot gnu.org> ---
I believe the original example is essentially IFNDR and it's a good thing that
GCC diagnoses it proactively. The requirement k<T>(); will always fail for
every choice of T because there is no declaration of k visible to the template,
and the call isn't eligible for ADL since there's no arguments.
