A function call is an lvalue if it returns an lvalue reference meaning the following fucked up and evil code compiles:

int& get_seven() {
  int seven = 7;
  return seven;
}

int main() {
  get_seven() = 8;
}

@wallhackio okay but what does that actually do

@aescling i'm not completely sure

@wallhackio that has to be a memory integrity error

@aescling it does run.......

@wallhackio try running it under valgrind
