There isn't any. Why do you ask? I am and I found Xah Lee's tutorial
helpful.  I didn't assume he was or wasn't. I just added the link
to allow the OP to evaluate the usefulness himself.

Since you seem to be quite sure I am doing a mis-service I think its
only fair to defend myself and point something out -

If you read the paragraph above I specifically say:

`----

So I am somewhat surprised by your reading of my reply.

It would me too. But I didn't and nothing I said indicated I did. Had he
been though it might be useful. Others read this threads too following a
Google.

If Lisp was your first language great. There are many, many more where
it won't be. eLisp is a minority language and people familiar with
others will frequently be looking to learn a little. This is obvious
from reading this group and the #emacs irc channel.

Yes, that is all really nice. But others might benefit from the
link. You seem quite adamant that it should not have been posted. I can
not begin to think why. It is another eLisp resource that people MIGHT
find useful depending on their skill levels, background and needs. Let
them decide.

I don't. But I also don't decide for the person asking. Providing the
link can do no harm.

Ir is often forgotten that SOME programmers are looking for a quick and
dirty introduction in order to do one thing and one thing only. They
have neither the time, resources nor desire to learn something like Lisp
from the bottom up and some readily available patterns and programming
snippets are more than enough.

i can only state once more : I personally found Xah Lee's tutorial
useful and consider that others might too.
