<H3><a name="Perl5_nn23"></a>26.4.9 Operators</H3>
<p>
As of version 1.3.27 SWIG automatically renames the most common C++ operators, and maps them into the perl module with the proper 'use overload ...' so you don't need to do any work.
</p>
<p>
C++ operators can also be wrapped using the <tt>%rename</tt> directive. All you need to do is
give the operator the name of a valid Perl identifier. For example:
</p>
<p>
The following C++ operators are currently supported by the Perl module:
</p>
<div class="code">
<pre>
%rename(add_complex) operator+(Complex &amp;, Complex &amp;);
...
Complex operator+(Complex &amp;, Complex &amp;);
</pre>
</div>
<p>
Now, in Perl, you can do this:
</p>
<div class="targetlang">
<pre>
use example;
$a = example::new_Complex(2,3);
$b = example::new_Complex(4,-1);
$c = example::add_complex($a,$b);
</pre>
</div>
<p>
Some preliminary work on mapping C++ operators into Perl operators has been completed. This is covered later.
