True. On the other hand, "all arrows bind |this|" is also quite simple and easy to remember. If the use-case for block bodies with bound |this| is uncommon enough, we > could just say "use a good ol' function expression long-hand." Would that > be so bad, compared to the alternative you're suggesting? I think that use case is quite common, if we include function expressions that don't care about |this|, bound or not. For Node's js source (as of a few weeks ago), there are 456 function expressions which are algorithmically convertible to bound |this| forms (because they either currently explicitly bind using self = this or because they don't care about |this|). Of those, about 60% are multi-statement. As an example, the following function expression is multi-statement and since it doesn't care about |this|, it can be rewritten using a (shorter) bound |this| form: https://github.com/joyent/node/blob/master/lib/http.js#L1633-1652 kevin
