Ah, thank you for the explanation. I like not breaking code. :-) LGTM aside from a possible simplification for the matchers.

+  Finder->addMatcher(varDecl(TopLevelDecl).bind("top"), this);
+  Finder->addMatcher(functionDecl(TopLevelDecl).bind("top"), this);
+  Finder->addMatcher(recordDecl(TopLevelDecl).bind("top"), this);
+  Finder->addMatcher(typeAliasDecl(TopLevelDecl).bind("top"), this);
+  Finder->addMatcher(functionTemplateDecl(TopLevelDecl).bind("top"), this);
+  Finder->addMatcher(classTemplateDecl(TopLevelDecl).bind("top"), this);
+  Finder->addMatcher(typeAliasTemplateDecl(TopLevelDecl).bind("top"), this);
----------------
Can we mix these together with `anyOf()` so we're not adding so many matchers? e.g.,
```
Finder->addMatcher(anyOf(varDecl(TopLevelDecl), functionDecl(topLevelDecl()), ...).bind("top"), this);
```
