I agree that an option for alists would be nice.

However, you could use `map-nested-elt' to traverse any map (hash-table
or alist):

    (map-nested-elt my-table '(key1 key2 key3))

map.el also provides `map-let' and a "map" `pcase' pattern, which can be
used to traverse nested hash-tables (and also works on alists, or a mix):

    (pcase-let (((map ('key1 (map ('key2 (map key3))))) my-table))
      ...)

Nico
