accessing a non-existing element in C++'s map/unordered_map 
inserts the default instead of raising an exception

int main(int argc, char *argv[])
{
     std::unordered_map<std::string, int> test;
     std::cout << test["hello"] << std::endl;
     return 0;
}

prints 0

void main()
{
     int[string] test;
     writeln(test["hello"]);
}
