Yes, we intentionally do not want things to be annotatable.  In fact, 
Function being annotatable is a wart due to the way the code generator 
currently works.  In general, we prefer to keep data in on-the-side maps 
instead of attached to the IR.  The mailing list has archives of extensive 
discussion about this sort of thing.
