  This is a simple LRU cache I made to get my hands on generics which is available in the go 1.18 beta. Feedback is welcome :-)

  You'll probably be a lot better off a) preallocating the elements so your memory is nicely contiguous, b) tracking indices and not pointers. If I wanted to pay 24b overhead per item I'd use an `interface{}`. :)
