no (or as little as possible) undefined behaviour comes to mind.
Initialization of values in D follows that.
Slice appending does not (and will remain so also with LRU cache).
LRU cache improves the current status quo, but is still a cludge: 
undefined behavious in some corner cases, undefined optimization 
behaviour...
It improves things, but cannot be trusted in general, thus a clean 
library type is still needed imho.
