It would need to be typeof( (typeof(type)) (type) ) to not be that
constrained on what kind of expressions it accepts as arguments.
Anyway, it won't work with array types at least,
int a[10];
typeof ((typeof (a)) (a)) b;
is an error (in both gcc and clang), while typeof (a) b; will work
(but not drop the qualifiers). Don't know if the kernel cares or not.
