reject doesn't mutate! <3

fair point. In which case x = hash.reject(&:bad_thing?) Why complicate matters?

I deleted the toot because reject used to return an array of entry arrays but now it actually returns the hash

and I got that wrong at first because reject no longer decomposes {|(k,v)|} correctly, it passes both {|k,v|}. Good times

`FromIterator` is a good interface to have exist which is separate from `Iterable`/`Iterator`. I wish Ruby had it.

sounds a bit like the Ennumerable module? Or am I missing something?

Enumerable just assumes that you want an Array back.

so how does FromIterator work?
