@grynspan @mjtsai @tapbot_paul using the length is a good idea. We change that.

@Catfish_Man@grynspan@tapbot_paul Would be nice for it to use the length for NSData. I wonder why that wasn’t done. -
@mjtsai@grynspan@tapbot_paul just an oversight afaik. Not all that many people hitting that code path. Should be a safe fix. -
@Catfish_Man Cool. For NSArray, seems obvious to pick a few elements to combine. Am I missing something? NSDictionary seems harder. -
@mjtsai@Catfish_Man Arrays containing mutable objects? -
@rosyna@Catfish_Man I think mutable objects make an array invalid as a key regardless of the hash function because they break equality. - Show more

@grynspan@mjtsai@tapbot_paul ugh how do I words. We *should* change that. -
@Catfish_Man@grynspan@mjtsai not having length killed performance on something we were doing, which is why we noticed.
