The difference is that the original behavior allowed room to transform the mutated object into an object which *could* be safely cached in a "downstream" seq, while the new behavior pumps the iterator through 32 mutations before user-level code has a chance to see it. Contrived example using the J

In what way is it broken? Both before and after wrapped a mutable iterator into a caching seq. The new one is different in that it chunks so reads 32 at a time instead of 1. However combining either with other chunking sequence operations would have the same effect which is to say that using tha
