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. Anything I did with it so far was a result of trial-and-error procedures. Are there any good ideas around how to remedy those deficiencies?
