This looks brilliant. I have written some sketchy stuff that searches
an a-list in the normal way, but if the a-list lookup fails and the tail
is not the empty list but a SRFI 69 hash table, then search the hash table,
on the assumption that there's a certain amount of stuff that has to be
functional and then there are lots of global keys that are maybe mutable,
maybe immutable, but anyway should be searched fast. This looks like a
*much* better approach.
