#include <stdio.h>
struct foo {

int dummy;

int main()
{
printf( "Size of foo: %d\n", sizeof( struct foo ) );
printf( "Size of foo.bar: %d\n", sizeof( ( ( struct foo * ) 0 )->bar ) );
return 0;

It's not perfect, but at least it reads better than your syntax ;-)
Oh, and of course C++ groks this perfectly:
----
#include <iostream>
using namespace std;
class foo {
public:
int bar;
int dummy;
};
int main()
{
cout << "Size of foo: " << sizeof( foo ) << endl;
cout << "Size of foo::bar: " << sizeof( foo::bar ) << endl;
return 0;
}
----
so maybe you should switch language :-P
