The horse has left the barn. > On the spreadsheet, how much red was accumulated on "strict with"? "Reformed with" was an attempt to restore lexical scope by exact type annotation. That's what people voted down, not the ES1-3 "with" statement. > IIRC, it was a lot. Does anyone think "with" is a valuable construct? > Why? Anyone care to post a defense of "with"? There's no point tilting at windmills. "with" is absolutely required for web compatibility, and it won't go away for a long, long time -- if ever. It's insanely popular. It's not only common in extant or "legacy" JS, new uses crop up all the time. You might hope to cause "with" to go away by forbidding it in a new, optional ES3.1 mode, but the chances of that seem at least as small as the chances that "with" popularity will simply make people avoid such a strict mode. /be _______________________________________________ Es4-discuss mailing list Es4-discuss@mozilla.org https://mail.mozilla.org/listinfo/es4-discuss
