But I hope so. "sometime". On our agenda is releasing Emacs 23 with unicode-2. It is not merged yet. Then there is some unspecified fate/timeline for bidi support. Pushing out lexical scope will be a somewhat harsh move with regard to code compatibility and stuff. So it better happen _early_ in a release cycle, in order to let third-party stuff catch up. Personally, I would love to see code like `(lambda (x) (1+ ',y)) go away rather sooner than later (it is not byte-compilable for one thing), and (lexical-let ((y y)) (lambda (x) (1+ y))) is not really something I fancy. And anyway, when the binding goes, so does the value. -- David Kastrup, Kriemhildstr. 15, 44793 Bochum
