Why can't you see these links on the first page returned by Google?

http://steve-yegge.blogspot.com/2008/01/emergency-elisp.html

There's even the "Emacs Lisp for Perl Programmers"
http://obsidianrook.com/devnotes/elisp-for-perl-programmers.html on
it.


Granted, contrarily to what I expected, there's no cheat sheet for
emacs lisp, just for emacs.  This is not bad, since the later would
help you know how to get help about the if operator, (typing C-h f if
RET).

In anycase, you should have been able to find at least the two links
above that are accessible from the first page of results given by
google.

Yes, that's a funny side effect.   That's why google search should be
done first! ;-)

The problem is that you shouldn't have to ask what syntax is if in
lisp, if you knew the first thing about lisp.  You can realy learn all
there is to know about lisp in five minutes. (Of course, then you need
a lifetime to ponder the consequences, but nonetheless, five minutes
is all you need to know it all).

Just tell us when you have five minutes to learn all there is to know
about lisp ;-)
