[C++-sig] functions whose return type is a pointer

I would love to prepare a patch for the opaque pointer issue if someone
could explain the proper procedure to me.

Cheers,

For this you will have to have a class_<B> statement also.

P.S.: Recently there was a thread on wrapping "opaque pointers":

http://mail.python.org/pipermail/c++-sig/2003-January/003207.html

I am not sure what the current status of the corresponding patch is. Please
check the archive for the whole story if this sounds interesting.
