<p>A very important data type in Scheme—as well as in all other Lisp
|

|
|
dialects—is the data type <em class="dfn">list</em>.<a class="footnote" id="DOCF8" href="#FOOT8"><sup>8</sup></a>

|

<p>This is the short definition of what a list is:

</p>
|
||
|
|
<ul class="itemize mark-bullet">
|
||
|
|
<li>Either the empty list <code class="code">()</code>,
|
||
|
|
|
||
|
|
</li><li>or a pair which has a list in its cdr.

<p>Strictly speaking,
|
||
|
|
Scheme does not have a real datatype <em class="dfn">list</em>. Lists are made up of
|

|
|
<em class="dfn">chained pairs</em>, and only exist by definition—a list is a chain
|
||
|
|
of pairs which looks like a list.</p>
