That is clear from context: "we haven't specified ...". > Brendan seemed to invite discussion about the semantics of let. I was trying to get comments from users of JS1.7's let forms. The keyword argument was not interesting to me. But this is es-discuss, we can talk about whatever we want to do with ECMAScript futures. > If the committee has reached consensus then those outside the > committee > could save time and keystrokes and focus on other things where > there is > need. Rather than change the topic to complain about something that hasn't happened (no ES4 spec yet), why not respond to the substantive point: let != function-expression-call? > How do outsiders know which proposals have reached committee > consensus? I said that many on the committee were in favor, notionally and in some details, of much of JS1.7's "convenience features", and some beyond: let as new var destructuring assignment and binding forms generators (modulo keyword issue) expression closures spread operator rest parameters optional parameters So not everything is a blank slate in TC39 for ES-Harmony, nor should it be. /be _______________________________________________ Es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
