I think it's a good enhancement. C++'s good old enum has been 
instrumental in finding a few bugs and clarifying a few interfaces in a 
project at work. Based on that experience I'd say that there's a chance 
more restrictive is better. We need to find a principled way to define 
semantics though - if we disable comparison it really means we're 
disabling implicit conversion.
