Huh? Is there any difference other than the second one can take a NIL value? > Lastly, passing by reference rather than by value is much faster. That's what "const" has been invented for: Letting the compiler decide the most efficient way. Not to mention, expressing your intent: You don't change it, say so: "const". You change it, say so: "var". You initialize it, say so: "out". If you just take the pointer no-one knows if the value is in/in out/or out. That's clearly not a "benefit".
