Thanks, Michiel!

Great idea, and one that may be more beneficial to the masses. 
Currently, I implement a lru_cache, but it is specific.  I believe just
a little work would make it more generic, as you suggest (I kinda have
that as I allow using FILE* or int - handling each specially, but having
a policy manage those would make it very generic).

I'll see if I can make some time over the weekend to work on it (between
my son's baseball, and all the spring yardwork -- which includes moving
ANOTHER 5 tons of pea gravel, wheelbarrow by wheelbarrow).
