For the purposes of this introduction, you do not need to worry too much
about whether something is a special form, macro, or ordinary function.
For example, @code{if} is a special form (@pxref{if}), but @code{when}
is a macro (@pxref{Lisp macro}). In earlier versions of Emacs,
@code{defun} was a special form, but now it is a macro (@pxref{defun}).
It still behaves in the same way.
The final complication is this: if the function that the
Lisp interpreter is looking at is not a special form, and if it is part
of a list, the Lisp interpreter looks to see whether the list has a list
