With the change to use `ArrayRef` above, I find constructing the array as part of the call slightly more readable:
```c++
    Attr *ResourceClassAttr =
        HLSLResourceClassAttr::CreateImplicit(Record->getASTContext(), RC);
    Attr *ResourceAttr =
        HLSLResourceClassAttr::CreateImplicit(Record->getASTContext(), RC);
    addMemberVariable("h", Ty, {ResourceClassAttr, ResourceAttr}, Access);
```
