GCC supports writing methods such as

void T::fn () __restrict__

in the scope of whose bodies, this is a restricted pointer. Considering the fact that __restrict__ is not used in function overload resolution - in which cases is it useful to add this qualification?

    If you understand what this qualifier does, then it becomes self-evident when "it is useful to add this qualification". – Sam Varshavchik Nov 21 '16 at 11:38
