Description
We may use a 8-char (sizeof(Char*)) buffer to store small keys (via a union). However, we must think how we notice this was done. Most importantly, we should NOT copy constant keys - on the other hand: if the string is smaller, isn't that even better (also from a data spatial locality PoV).

Research direction
Start by locating the subobj representation and the code paths that store and copy keys; the issue names no files or tests. Establish how inline keys would be distinguished from constant or allocated keys, then define tests and completion criteria for avoiding malloc without changing key behavior.
