When I do this, I get the following warning a few times:

```
/home/nick/llvm-project/lld/wasm/SyntheticSections.h:165:7: warning: ‘lld::wasm::ImportSection’ has a field ‘lld::wasm::ImportSection::importedGlobals’ whose type uses the anonymous namespace [-Wsubobject-linkage]
  165 | class ImportSection : public SyntheticSection {
      |       ^~~~~~~~~~~~~
```

Do you still prefer this approach?
