[cfe-dev] Reference counting

when developing with clang/llvm I have quite a mess with
pointers, references, llvm::OwningPtr and get()
My suggestion would be (which won't get accepted due to the huge
code base) to have a llvm::Object that has a reference counter and
then a llvm::Pointer that increments/decrements the ref-count inside
Then for every class there has to be decided if it derives from Object and
always allocated with new and always passed as Pointer<>
or a struct and never allocated with new.
I use this scheme quite long now and never have problems except ring
references in complex graphs which have to be broken manually.
