>Description:
The following fails to compile.  Workaround is to declare forward reference to class outside the template.

template<class Info>
class Table {
  public:
    bool Lookup(int name, class Detail* detail, Info* info) const;
    void Insert(int name, class Detail* detail, Info  info);
};

class Detail {
  public:
    int stuff;
};

template<class Info>
bool Table<Info>::Lookup(int name, Detail* detail, Info* info) const {
    return true;
}

template<class Info>
void Table<Info>::Insert(int name, Detail* detail, Info info) {
}
