To me it's a bit strange that `SymbolVisitor::VisitSymbol` was a public virtual
method, but here you override it with `private` visibility. If I understand
correctly, this code will still behave correctly, but for the sake of clarity
I'd prefer moving this override after the `public:` marker unless you have a
concrete reason for not doing so.
