// Abbreviation: alias for a long complex template type. 
using Cache = std::unordered_map<std::string, int>;

int main() {
    Cache scores;  // Using the abbreviation

    scores["Isla"] = 100;
    scores["Luke"] = 95;

    for (const auto& entry : scores) {
        std::cout << entry.first << ": " << entry.second << "\n";
    }
}
