   reference.  You should only be able to take the address of a variable.
   Maybe taking the address of a constant copies it?  What about virtual 
   function tables?  Maybe a const pointer would be better...
-* Structures should be accessed something like this: ubyte is ok.  Limits 
-  structure size to 256 members.  This can be fixed later by either: 
-    1. adding varient that takes ushort
-    2. Splitting structures into nested structures each of half size
-  <float> %f = load *{int, {float}} Str, 1, 0
-  store float %f, *{int, {float}} Str, 1, 0

-  ConstPool.dropAllReferences();
-  ConstPool.delete_all();
