The tweak in the buildArrayIdent() retains backward compatibility. a) If no element upcasting exists in array operation, the generated function name is not changed. double_res[] = double_val * double_arr[]; // _arrayExpSliceMulSliceAssign_d b) If upcasting slice elements is necessary, it will be encoded by the postfix "Of" + element-type-deco double_res[] = double_val * int_arr[]; // _arrayExpSlice'Ofi'MulSliceAssign_d 2. Even if the whole array operation requires double element, the sub array operations can be processed by int. double_res[] = (int_val ^ int_arr[]) * double_val; // typeof(int_val ^ int_arr[]) == int[] https://github.com/D-Programming-Language/dmd/commit/22611aa7eda98705a5661f0df424434a73b3c837 Merge pull request #4218 from 9rnsr/fix12780 Issue 12780 - Multiplying integer array by scalar double fails --
