`@safe` by default. What about `@pure` and `immutable` by default?

In order for me to articulate it correctly and completely, I'd 
have to basically write the DIP in this forum thread.  I'm not 
prepared to do that at this time.  As I said, I still need to 
think it through, even for myself.  I'd prefer to leave that 
discussion for the DIP review.

At the moment, I just need to know if, for the benefit of D in 
the long term, we want `pure` and/or `immutable` by default so I 
can clarify the scope of the DIP.

Thanks,
Mike
