"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.
