== extend task for Associative Arrays, Mappings, Dictionarys? ==
I'd like to extend this task to support Associative Arrays using the Lisp method of Cons Pairs:
((key1 . value1) (key2 . value2)) for { key1:value1, key2:value2 }
i think it is better to add it as Extra Credit to this task instead of creating a new task for it because a new task would require all of the code that this task needs, and then we'll get people wondering if the tasks should be merged.
i am aware that (a b) is equivalent to (a . (b)) in Lisp and therefore any list could be treated as an associative array, however for the purpose of this task (and for the usability as an interchangeable data format, we could just require that a pair with a list as value be written as (a . (b))
for the same reason a solution in lisp better ought to use a hash type when reading the data.
