3.14.5 AST Objects
</H2>

<P>
AST objects returned by <tt class=function>expr()</tt>, <tt class=function>suite()</tt> and
<tt class=function>sequence2ast()</tt> have no methods of their own.

<P>
Ordered and equality comparisons are supported between AST objects.
Pickling of AST objects (using the <tt class=module><a href="module-pickle.html">pickle</a></tt> module) is also
supported.
