Ah, I see, thanks for the explanation. The constructor actually lives in
"SymbolOccurrence". T
I'd like to use a more familiar way: `namespace clang { namespace tooling { ...
} }`

Comment at: lib/Tooling/Refactoring/Rename/USRLocFinder.cpp:398
Visitor.TraverseDecl(Decl);
- return Visitor.getLocationsFound();
+ return std::move(Visitor.getOccurrences());
}

Ok, didn't notice that `getOccurance()` returns non-const reference.
I think the method `getOccurances` may have potential effect -- the clients
could change the Occurences member variable of USRLocFindingASTVisitor, after
getting the non-const reference.
Another option is to rename `getOccurances` to `takeOccurrences` and return by
value:
```
SymbolOccurrences takeOccurrences() { return std::move(Occurrences); }
```
What do you think?
