I thought that we agreed to use a single function in place of two for low-level library functions to: - reduce the amount of code - avoid possible memory errors - avoid the need to ignore functions in the swig interface (which has been a source of bugs). I advocate the shared_ptr interface over extra work and complicated memory issues. I don't see an advantage to a reference version in parts of the code that only advanced users will see.
