Yeah, true in general, though it is possible to have a struct be 
very similar to a reference type. Consider:

struct WrappedClass {
    Object obj;
    /* and whatever other methods, but no more data */
}

It's still a value type, but the only member is a reference, so 
you can use it the same way as any other reference type; it works 
the same way as Object itself.

So struct is flexible in the value vs reference type regard too.
