Agreed. Here is an excerpt from a comment from one of our header files:

"We could not use boost::unique_ptr because the version of the Boost 
library that we currently use does not include it."

Of course. We had definitions like the following as well, where the C 
objects are stored in:

typedef vector<CPtr> MyCs;

I think so. :) Maybe we should pass weak_ptrs around instead of 
shared_ptr. Anyway... That's old code and this is a D newsgroup.
