Is there a way to do multiline comments in Common LISP/MCL?
/*
For example, these two sentences would be comments if I was programming
in Java. However, I am not using Java because I'm trying to learn LISP
and since I don't know how to do this in LISP I am stuck using a lot of
semicolons for now. :-)

Thanks,
Mari

Hi Mari,
Everything placed between a #| and |# is ignored.
Two very good introductory texts on Common Lisp that I've used are:
1) "ANSI Common Lisp" by Paul Graham. Prentice-Hall, 1996.
ISBN: 0-13-370875-6
and 2) "Programming in Common Lisp" by Rodney A. Brooks. John Wiley & Sons
1985.
ISBN: 0-471-81888-7

this is not so, actually. your statement could easily be construed to
mean that the a #| is terminated by the first following |#, but #| and |#
comments nest. this means that it is quite safe to comment out an
arbitrary amount of code with #| ... |#, quite unlike /* and */ in C,
which are useless if the region you wish to comment out may contain
another comment.

#| Yes,
there is.
#| And yes, it nests. |#

--- KMP's Style Recommendation Notes Follow ---
Btw, if you are commenting out code, you are stylistically
advised to use #||....||# since some editors think that |...|
occurs in balanced pairs (like "...") and that parens don't
have to balance between them; using double-||'s won't affect
Lisp at all, but will make some text editors do better paren
balancing. When in #||...||#, I encourage use of ;'s or
#|...|# for text comments since if the #||...||# is removed,
you should have parseable-code left.
#|| ;The entire rest of this message is useless
;and has been commented out.
#| 1) This is a comment.
2) It's not a comment containing code.
3) Parens needn't balance.
