Thanks for your comments and the example. I think using `OpaquePtr` is safe,
since `DenseMapInfo<clang::QualType>` in
`clang/include/clang/AST/TypeOrdering.h` also uses `OpaquePtr`. I initially
chose `OpaquePtr` because it is more lightweight. I’ve now submitted a commit
that uses `QualType` directly instead. Which approach do you think is better?
