mix() has many overloads: $genType mix($genType x, $genType y, $genType a); $genType mix($genType x, $genType y, float a); $genHType mix($genHType x, $genHType y, $genHType a); $genHType mix($genHType x, $genHType y, half a); $genType mix($genType x, $genType y, $genBType a); $genHType mix($genHType x, $genHType y, $genBType a); $genIType mix($genIType x, $genIType y, $genBType a); $genBType mix($genBType x, $genBType y, $genBType a); The top half were simple to implement via `evaluate_3_way_intrinsic`. The bottom half--`x, y, $genBType`--required adding basic support into `evaluate_n_way_intrinsic_of_type` for mixed argument types, since `x` and `y` could be of any numeric type, but `a` is always boolean. Fortunately, this didn't require major changes.
