Find the best viable function on this overload set, if it exists.
Computes the best viable function (C++ 13.3.3) within an overload candidate set.
Loc | The location of the function name (or operator symbol) for which overload resolution occurs. |
Best | If overload resolution was successful or found a deleted function, Best points to the candidate function found. |
