I don't know anything about the special meaning of ampersands in XSUB
arguments. Is that mentioned somewhere in the docs?
In `perlxs` and `perlxstut`, search for "semantic"
(there's a typo in perlxstut).
Other than that, C++
references are probably best avoided. It severely collides with perl's
garbage-collecting when you use C++'s default memory allocator and then
pass references to this object around. So the only safe way is to use
'new' and pass the pointer instead of the reference. C++ wont mind.
Might explain a certain segfault I was screaming at last night...
That's a good idea, to wrap the pointer up in new.
(Mozilla::DOM is the module I'm doing, if anyone's curious.)
