(SHIT! This damned keyboard just doubled a ^C and sent you all some
more trash to delete! Most of you get TWO copies!)
1) Yes, I prefer ";" as the way to write a comment too. But there are
things that you cannot do with it that you can do with "#|". If MIDAS
programmers prefer the ";" comment and tend to use it when they can,
then I suspect the same thing will remain true of Lisp programmers.
2) Yes, It is intended that the things should nest. I agree that
editors won't be able to deal with this correctly, but that is a poor
reason to screw ourselves. People who use "/*" in PL1 have complained
bitterly for years that the damn things don't nest correctly.
3) About slashification. I didn't think it was necessary since you
can always comment out a "|#" by typing "|/#" instead, but "/|#" is
better parsed by editors. So OK, slashification is now part of the
4) Anyone who uses
has just thrown away all the advantages of "#|". He might as well be
typing ";;;" at the front of every line. Editors will also get confused by
all the "|"s. For these reasons I expect that this will not be done.
(BTW, M-Q does understand ";;;" if you set the fill prefix, but that is
not always enough.)
5) How come nobody voted no the first time I brought this up?
