Actually, while MAPHASH->HASH may use imperative features *internally*,
externally it's behaviour is fully functional [or at least as functional
as the function over which it's mapping], and therefore I would call it
"as functional as MAPCAR" and let it go at that.

Now if it *mutated* the existing input hash table's values...  ;-}
