Second, I would consider it rude to tell an enthusiast FSF Emacs user to "upgrade" to XEmacs. Perhaps he does not want to use XEmacs for other reasons. It is very questionable whether these places would be made faster by the sole introduction of `lexical-let'. But, as I said, your guess is just as good as mine. -- Hrvoje Niksic <hniksic(a)srce.hr&gt; | Student at FER Zagreb, Croatia --------------------------------+-------------------------------- "A Real Programmer's code can awe with its fiendish brilliance, even as its crockishness appalls."
