// LRU cache that behaves like std::map with differences:
// * drops least-recently used items if necessary on insert to prevent size from exceeding max_size
+// * operator[], at, insert, emplace and find freshen existing entries
// * iterates from least- to most-recently used rather than in order by key
// * iterators to dropped items are invalidated
// * not all map interfaces implemented
