   In this case I suppose we only want to use the underlying object so we do 
not need to pass by value and we can use a raw pointer or a simple reference 
here. The only difference maybe is that if we decide later that we need to 
share the ownership with someone in the call chain we have the possibility. As 
I recall clang static analyzer usually suggests using shared_ptr const refs in 
these cases.
