What use would that be? If the programmer knows that a pointer in the function might be a null pointer, and wants to throw if that is the case, then the programmer can write "if (!p) throw nullptr;", or whatever suits their needs.

It would allow us to write one-liner functions like:

unsigned GetCOMportNumber(char const *const p)

{

return stoul( strstr(p, "COM") + 3 );

}

and also to write a one-liner like:

pInterface1->GetInterface2()->LastChild()->Release();

instead of:

if ( nullptr == pInterface1 ) return;

auto p = pInterface1->GetInterface2();

if ( nullptr == p ) return;

auto p2 = p->LastChild();

if ( nullptr == p2 ) return;

p2->Release();
