AFAIK the builtin associate array implementation exposes neither
such a function, nor other functions which you can use to
assemble this, so no, you cannot do this with only one lookup
(currently).
Though I can't see why it couldn't be added, seems fairly
straight forward.
The best you can do with the builtin associative arrays right now
is make sure that the `toHash` of your key type is cached.
