Internal LRU cache implementation

Hello internals, In my experience, LRU cache is a common pattern in userland. Each time I write one in PHP, I suspect that it would probably be much more efficient if it was implemented in C. If this is indeed a very common pattern, and it would be much more efficient implemented internally, is there any appetite for an internal implementation of LRU cache? I would suggest the following interface as a starting point: __construct(int size) resize(int n) get(scalar key) set(scalar key, value) remove(scalar key) Thanks for your time
