He meant that when you only have a single token it is parsed as PARAMTYPE and not varname.

EG:

void foo(int);

Thanks for pointing out my misunderstanding.

But we can make a compiler which can "understand" what we want it understand.

void foo(int); // this is just a declaration, not a definition

auto foo(a) // this is a definition, with a function body, they are different

{
}

No difference.

void foo(int)
{}

Is perfectly legal.
