I agree with Steven. Having the 'else' continue on with a scope that is already 
closed by } is very weird and unsettling.

You could argue that D already does this with static if:

     static if (x)
     {
         int x;
     }
     x = 3;

and that disturbs some people. But it is conditional compilation, and no other 
way around it has been proposed, and it has major benefits. (C++'s static if 
proposal does not allow this, a decision that I predict they'll come to regret.)

Adding more cases of this sort of thing should be approached with great 
trepidation, and is not justified if it is only a minor improvement.
