Which pure functional languages have assignment expressions, beyond
ones from libraries or your own code written in the lanuage itself
(e.g., Control.Monad.State) that are just faking assignment anyway?

does only that. (I'm always scratching my head over whether `=` is
doing binding or assignment.[1])
