Follow-up with a few more details... I will add: rename to hash-keys/values dict functions for the hash functions I added vector-set*! sequence-cons, sequence-empty, sequence-filter, etc for/sequence
Also, I thought of a better way than prop:procedure to get containers to implicitly ref... we could change apply and #%app. I don't think it would be slower because the code would already be on the slow 'error' path, but I don't have a strong opinion on if it is a good idea, so I don't plan on trying it out until further discussion.
