So you agree it is sufficient?  The confusion here is that you *seem* to  
be arguing for the inclusion of a feature which *appears* to be a sub-set  
of a feature we already have.  Thus, we assume you've got a reason for  
this, and we assume this reason is some problem with the feature we  
already have.

Which is what exactly?  That 2 features not-null and @disable this() are  
the same thing?  They're not, one is a subset of the other.  That they  
require the same compiler functionality, we all agree, but that's not  
really important or relevant.  What is relevant is whether NotNull can be  
implemented using @disable this, and you've agreed that it can.

If you have another point it's been lost or overlooked so please re-state  
it.
