Isn't that already covered by this?

dbg-macro/dbg.h

Lines 163 to 171 in f4e91b6

    
           template <typename P> 
        
           bool prettyPrint(std::ostream& stream, P* const& value) { 
        
             if (value == nullptr) { 
        
               stream << "nullptr"; 
        
             } else { 
        
               stream << value; 
        
             } 
        
             return true; 
        
           }

Or do you want dbg(nullptr) to behave differently? I think the nullptr literal is the only thing of type std::nullptr_t.

currently, dbg(nullptr) simply fails to compile (because it is of type std::nullptr_t and not P*`).

I think the nullptr literal is the only thing of type std::nullptr_t.

If calling with the actual nullptr literal is the only way to trigger this, we don't really need to add support - you are right.
