Re: ES3.1 Draft: 11 June 2008 version available
Hi, and thanks for any work on making ES3 better while we wait for ES4! One thing I miss form the targeted additions part of the spec is: function.bindEvent aka function.bindEventListener The difference from function.bind is that binded arguments are appended after instead of before the arguments when called. Example code for function.bind and function.bindEvent (where arguments is a true array): function.bind = function() { // Binds arguments to a function, so when you call the returned wrapper function, // arguments are intact and arguments passed to the wrapper function is appended. // first argument is 'this' and the rest is arguments var args = arguments, __fn = this, __object = args.shift(); return function(){ return __fn.apply(__object, args.concat(arguments))}; }; function.bindEvent = function() { // Same as bind, but prepends the arguments to the wrapper function var args = arguments, __fn = this, __object = args.shift(); return function(){ return __fn.apply(__object, arguments.concat(args))}; }; http://wiki.ecmascript.org/doku.php?id=es3.1:targeted_additions_to_array_string_object_date On Thu, June 12, 2008 2:01 am, Pratap Lakshman (VJ#SDK) wrote: I have uploaded to the wiki (linkhttp://wiki.ecmascript.org/doku.php?id=es3.1:es3.1_proposal_working_draft, see under Draft Specification) the current draft of the specification for ES3.1.

I'm trying to understand the nature of the ES3.1 - ES4 subset relationship that this committee has agreed to. p69 12.10. Disallowing the with statement in strict mode breaks the ES3.1 - ES4 subset relationship (we've found no compelling reason to ban it). How does having ES4 support *more* than ES3.1 supports break the subset relationship? - Sam Ruby ___ Es4-discuss mailing list Es4-discuss@mozilla.org https://mail.mozilla.org/listinfo/es4-discuss

How does having ES4 support *more* than ES3.1 supports break the subset relationship? Having ES3.1 strict mode forbid features that ES4 strict mode does not (but which are in both languages) feels like breaking the subset relationship to me. The reason is that program that is purely ES3 but has the strict mode pragma added could then be legal in one language but not the other, which seems problematic. To the extent that strict mode limits ES3-with-pragma programs, I think it should impose the same limits in ES3.1 and ES4.

Fair question. I don't recall that it has been spelled out carefully, actually. I'll take a stab at it in the morning. (Also, the ES3 - ES3.1 and ES3 - ES4 relationships are important.) Any useful definition will have to deal with bugfixes and security fixes (like global type names being read-only under some circumstances in ES4). --lars -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Sam Ruby Sent: 12. juni 2008 18:46 To: Lars Hansen Cc: [EMAIL PROTECTED]; es4-discuss@mozilla.org Subject: Re: ES3.1 Draft: 11 June 2008 version available I'm trying to understand the nature of the ES3.1 - ES4 subset relationship that this committee has agreed to. p69 12.10.
