What's the point of using a macro in circumstances where a portable, standard
conforming, safe-to-use, shorter-to-type, version _without_ using a macro
exists?

I.e. in case of a simple pointer initialization, why should one *ever* prefer 

void something()
{
    Foo *f = Q_NULLPTR;
    ...
}

over

void something()
{
    Foo *f = 0;
    ...
}

?

For the sake of keeping this part of the discussion simple, I specifically
mean 'Q_NULLPTR, the macro', _not_ 'nullptr', and I specifically mean the
context of initializing a local pointer variable. So: Any advantage? Any
advantage outweighing the disadvantages?
