Maybe we can add this sentence to (info "(eintr) defun") or (info
"(eintr) Complications"), then add a cross reference to (info "(eintr)
Lisp macro"):
"Macro" is a construct defined in Lisp, which differs from a function in
that it translates a Lisp expression into another expression which is to
be evaluated instead of the original expression.

Sorry, I forgot it.

Maybe "another macro"?
I think there are not too many complications in this
introduction/tutorial. Lambda expression is in the appendix, and
closure and byte-code function are not mentioned. Since macros in
explained in the main body of this tutorial, I don't think it is more
clear to lie.

Thanks, I will do it the next time. (Is there anyway to amend this
commit log?)
