Which would imply that there is actually an amount of C++/XS tricks
available in a variety of places. The only two I know of is perlxs.pod
whose information on that matter are fairly puny, and - of course -
existing XS modules written in C++ on the CPAN.
What would be some (good) examples of XS modules using C++?
Using http://search.cpan.org and
cpan> i /c\\+\\+/
didn't find anything. I also have an rsync of CPAN which could
be trawled through by gunzipping every distribution and grepping
Makefile.PL for c++, but I didn't try that yet...
Searching on http://perlmonks.org showed a couple relevant threads.

For the most part, it's pretty straightforward,
but for example how do you deal with passing values
into methods by reference? The ampersand (&) has a special
meaning for XSUB arguments. And return values with references,
since that seems to not work in typemaps (might've been my
mistake, though).
