The function is presumed to take zero or more arguments, which are used in
a tuple as the key for the cache. Hits are served directly from the cache;
misses use the function body to generate the value.
The wrapped function has an additional member, a callable called
"invalidate". This can be used to remove individual entries from the cache.
The wrapped function has another additional callable, called "prefill",
which can be used to insert values into the cache specifically, without
calling the calculation function.
