No, I think he means something like:
(*((*((*((*f)()->g))()->h))()->i))()
but I can't recall the relative priority of '*' and '->' in
the above, so I may have added unnecessary parens.
Actually trying it, while the
above does the right thing,
I can also get the following to compile with a modern compiler
(*(*(*(*f)()->g)()->h)()->i)();
So maybe that was the answer?
I guess I'd have to question why someone would wish to write
such a construct, as error handling seems awkward. Even in
the modern form.
