[Interest] Qt based LRU container?

I wrote a ordered map sometime back using a QHash and QLinkedList.


In the 'examples' section, I've implemented a simple LRU cache using
the ordered map.

Once the capacity of the cache is reached and a new item is inserted,
we take the first element of the ordered map, which is the least
recently used item, and remove it.

You could easily modify this code to emit a signal when this eviction happens.
