That looks nice. On the topic of hashes, one thing that always bugs me about the current hash API is the confusion between 'hash means hashequal' and 'hash means any kind of hash table'. For example, (hash? (hash ...)) => #t (hash-eq? (hasheq ...)) => #t (hash-eq? (hash ...)) => #f all as you expect. but (hash? (hasheq ...)) => #t I'm not sure what the best way to resolve this tension is. One thing that would help would be to add `hash-equal?', but I'm not sure about the name. -- sam th sa...@ccs.neu.edu _________________________________________________ For list-related administrative tasks: http://list.cs.brown.edu/mailman/listinfo/plt-dev
