Everyone seems to know that the obscure mini-language called "XS" is the standard way to wrap a C library for use in Perl code. Curiously, the mere thought of XS appears to strike fear in the heart of experienced developers. To add insult to the injury, the use of plain XS to wrap C++ code is barely documented.

Mattia Barbon must have had similar thoughts when he wrote the Wx bindings for Perl, thus XS++ was born. It offers a friendlier syntax for wrapping C++ classes and methods that is reminiscent of plain C++ headers with some annotations to fine-tune the Perl-facing API. It automatically converts C++ exceptions to Perl exceptions and helpfully takes care of many of the hoops one would ordinarily have to jump through.

The presentation introduces the audience to XS++.
Some advanced topics covered may require modest familiarity with XS or C++, but the basic concepts should be accessible to intermediate Perl programmers.
