C++ code:

class A;

template<typename T> class Visitor {

    void VisitCallExpr(A *CE) {
        return static_cast<T*> (this)->VisitExpr(CE);
    }
};

int main(int argc, char** argv) {

    return 0;
}

Problems:
1. Hyper link from "VisitExpr" go to beginning of file
2. Completion is available inside "VisitExpr" with empty element.
If completion is applied, the result is wild:
VisitTemplateBasedReferencedObjectResultItem for lastType=Visitor::T*, textAfterType=Expr
