 How often does this happen? 
 Additional Information:
 If we don't inherit class A from MarshalByRefObject, CSC compiles the code 
 without any problem.

+Ugh, thats nasty. What is happening is that the following code:
+needs to compile into
+ldloc a
+ldflda point
+call IsEmpty
+Because value types always get their methods called with the argument 
+being byref.
+One interesting point, what happens if you say
+where a is a MBRO, point a value-type and x a field. In the code, it 
+would look like:
+ldloc a
+ldflda point
+ldfld x
+However, you can't do `ldfld'
+I have the feeling that in this case, msft would copy point into a 
+local so that you could do the correct thing.
+Another question: if you have
+struct X {
+   static X Foo { get {...} }
+   int Y { get { return y; }}
+   static int y;
+And say X.Foo.Y, will it allow that? The return value from X.Foo can 
+not be passed byref.
