DeepEqual is simply inappropriate here. It's fundamentally problematic to do deep comparisons on types you don't have visibility into. You're not entitled to manage the fields, so you lack any guarantee that the implementation matches your expectations. Maybe comparisons require holding a lock, maybe there's a pointer to a shared object (like in this instance), maybe there's some reference to CGo stuff. It's just not the right way to go about it. If the language lacked reflection, how would you solve this problem?
