another workaround is to add a base case and then the rest of the parameter pack:
```c++
template <typename First, typename... Rest>
static LogicalResult foldTraits([[maybe_unused]] Operation *op,
                                [[maybe_unused]] ArrayRef<Attribute> operands,
                                SmallVectorImpl<OpFoldResult> &results) {
  return success((succeeded(foldTrait<First>(op, operands, results) || succeeded(foldTrait<Rest>(op, operands, results)) || ...));
}                  
```
